Living in a travel coach full time is a lot like a normal house. It takes some work, especially when seasons change. In 2020 we purchased a skirt kit for our 1979 Avion 34V. Skirts are a barrier installed between the bottom of the trailer and the ground. They can be made from rigid permanent materials, semi-permanent, or from materials that are easily removed and stowed for travel. Our skirt is 18# black vinyl. We travel regularly so a bulky rigid skirt wouldn’t be practical. We ordered a kit from idahocanvas.com.
Measuring our coach, we knew we wanted to be able to use two sections of the skirt as summer shade for the tires and wheel wells. That left a long skirt for the front section of the coach, and another for the rear. I ordered the skirts six inches longer than the distance to the ground, knowing we’d be parked on unlevel ground at times, and realizing we would not want a gap. The skirt kits come in different mounting styles, hook and pile or snaps. We chose the hook and loop type, and decided we would fortify the installation with twist snaps every 12”. After racing sailboats for a few years, I knew that twist snaps are easier to deal with than friction snaps. They don’t corrode and lock up, and you don’t have to pull hard on the vinyl to release them. I ordered black twist snaps, matching twist snap grommets, and the punch tool used to make a hole in the canvas that includes four slots for the grommet tangs to stick through. I also ordered two zippers for the wastewater access and four zippers for the two wheel wells. The black vinyl skirt kit arrived perfectly folded in a box that weighed about 40 pounds. As I opened the shipping box, I laughed knowing I’d never be able to get that skirt kit folded into anything that small ever again. Starting with the wheel well pieces, I cleaned and installed the 2” self-adhesive “hook” to the coach a couple of inches above the wheel well. The black twist snaps were installed in the center of the hook, every 12” with stainless black screws. It’s important to install the twist snaps, THEN install the grommets to match the spacing of the installed twist snaps. This is made clear in the kit’s instructions and makes a difference, so don’t rush in and install the grommets in the vinyl first, it will reduce the effectiveness of the whole install. I installed the first grommet and hung it on the first twist snap. Of course, being on a learning curve makes this seem slow and clumsy, but once the tools are all out and the pattern and rhythm are found, things start to move right along. Pulling the vinyl straight, but not stretched, to the next twist snap, I made a pencil mark on the center of the twist snap, used the punch tool to make the hole and slots, and installed the second grommet. Then the third, fourth, and so on. Within a short period of time, I had two really nice skirts covering both wheel wells. The front and rear skirts were more complicated, but having warmed up on the wheel wells I felt comfortable moving on. To prepare our coach for the front and rear skirts, a hanging point had to be chosen. Our coach has a piece of horizontal aluminum trim all the way around at the same height, down near the bottom. It normally has a black filler in it, that cover’s the screws. Most of the filler on our 40-year-old coach was damaged or missing, so I pulled the rest out. On Avions it’s a good idea to add some extra screws to this section. I drilled a hole and installed 2”, pan head, stainless screws about three inches from the original screws all the way around the coach. Each hole got a shot of Trempro 635 before running the screw in. With all the new screws installed, I primed the aluminum and let it dry a day or two. The kit comes with 2” wide, self-adhesive, hook to match the length of all the skirting ordered, so I cut the hook to 7/8” width, with a fresh utility blade and straight edge, and installed it into the trim where I had screwed, sealed, and primed. Using a plastic screen spline roller I must have rolled the entire length of the self-adhesive hook, all the way around the coach at least four times. Remember, most of these self-adhesive products stick at first, but are only load-bearing after about 24 hours. With that done, I shot the tiniest bead of silicone along the top and bottom of the hook to help keep out water and hold the edges in place. I know, everyone says never use silicone on an Avion, but it is a sparing application, and really makes the install complete.
After giving all this a few days to cure, I starting on the driver’s side, at the back of the wheel well, hanging the first 4 feet of the skirt, overlapping the wheel well skirt about 6 inches for added wind resistance. With the first 4 feet in place, I marked the position of the zipper that would connect the rear skirt to the wheel well skirt. Using the recommended contact cement, the first zipper was installed. Moving aft, I installed zippers on each side of the waste valve access, marking the needed zipper position, taking it down, cutting it, and gluing the two zippers in. Once I reached the back corner, I had to figure out how to get under and across the bottom of the belly pan to the other side of the coach. I made a little hanging tab for the section that runs across the bottom, at the back of the belly pan, then installed the 2” hook on the bottom of the belly pan after cleaning it well. At the passenger side of the coach, the pattern was repeated, rounding the curve and finishing the section all the way to the rear of the passenger side wheel well. Just like the driver’s side, a zipper was installed at this point. The front section of the skirt was again started at the driver’s side wheel well, forward end. Again, after hanging the first four feet, the zipper was glued into place and the long run toward the front of the trailer began. Since it’s a long straight run I found myself rounding the front curve and headed for the tongue A-frame pretty quickly. Once I reached the driver’s side A-frame member, I marked and cut a center slot, with a V at the bottom to fit snuggly over the frame member. Crossing the front a second slot was created for the center A-frame member, then just a few inches further a slot to accommodate the propane pipe and 7 pin connector pigtail exiting the front of the coach. All the while, carefully marking, punching, and installing the grommets and hanging the skirt as I progressed. The third A-frame member slot was cut and around the front, passenger side curve, and away we went. Skirt, tools, punch, and grommets. The last run was along the passenger side, under the door, and finishing at the front of the passenger side wheel well. Once all the grommets were installed, I took down the whole thing and fortified the slots for the A-frame members so the vinyl would not tear out in the wind. I also added a 5” piece of the hook to the top gap of the slot, so each side of the slotted skirt could be snuggly closed. Grommets were included in the skirt bottom when it arrived, but I added a few to fill in more tie-down points. There is also a place stitched into the bottom that a piece of pipe can be slid into for rigidity and weight.
All in all the skirt looks quite nice. And it definitely makes a difference in cold weather. It takes a couple of days for the ground temperature to warm up, but with almost no wind blowing under the trailer, the whole place is quieter and warmer. It also reduces the chances of freezing waste drains, which is about the only thing other than the high wind that keeps me awake at night. I picked up three big duffle bags at Savers, storing the two wheel well skirts in one, and the front and rear skirts each in the other two, making it easy to stow them in the van. After several times of installing and uninstalling the skirts, I have found them pretty easy to deal with. I’ve even put them up one time when we only parked on a driveway for two nights, knowing it was going to be windy and in the 20s. The whole thing has just become part of the checklist I use. I think the coach looks handsome with the skirts too. They are not totally impervious to high wind. We are in Oklahoma right now, and as I type this, sitting through a wind advisory with 55 miles an hour gusts. The skirt billows a little, but the grommets and ground stakes keep it in place nicely. You may be wondering about accessing the lower “basement” storage boxes, and that’s no problem. The turn snaps and zippers make it easy enough to loosen a section above the access door I need to get into. Since I put a zipper on both sides of the waste drain access door, that whole panel can be removed so waste water doesn’t get on the vinyl. I hope this helps, and if you live full-time in your Avion or another travel coach, I think this is a nice upgrade. If you have any questions, just post them below, or send me an email at firstname.lastname@example.org.
Happy travels friends!
PS. Just before publishing this article, we were in the coldest weather we have stayed in so far. Here in Maysville Oklahoma, it reached -12F below zero at night, and was in the single digits for severals days. Before the temperatures fell below 10F degrees, I emptied the waste tanks. We use a composter toilet, so the black tank stayed water free, and I put a dishpan in the kitchen sink, and a basin bowl in the bathroom, so no water went down the drains. Since it was super cold outside, about all we did was burn a fire and work inside, so we didn’t use the shower for a few days. This left only the fresh water tank to keep thawed. I used a tiny, thermostat controlled heater inside the waste dump valve access. I think things would have been fine without it, especially since the furnace has a 4″ duct blowing into the belly pan. The empty waste plumbing meant that I didn’t lay awake at night worried about the plumbing freezing, or worst yet, breaking. We were both amazed at how well the coach felt during the super cold weather. The floor was comfortable, none of the indoor plumbing supply lines froze, and with the help of the small electric heater in the back, and the wood burning stove, the only time the furnace ran was at night. Since a few inches of snow had fallen, the skirt was weighted and sealed to the ground. The one time I did check under the coach, I stuck my hand in a zipper in the skirt, to find it warm inside. The skirt did a great job, and is really worth the investment.
