Over the past year, I have improved upon my trailer skirting. I knew I wanted it to be inexpensive, easy-on, easy-off, and compact enough to be easily portable. I think I have finally hit on a working combination. Here is how I made my current Portable Trailer Skirt.
When we got the Minnie, we started off with foam board and heat lamps. This necessitated being hooked up to electricity to run the heat lamps. My new skirt keeps the salt-water charged waste tanks thawed down to zero. Then it’s time for some supplemental heat down there. Or preferably a move to warmer temps.
Materials for the Portable Trailer Skirt:
• 4, 12” x 100’ rolls of bubble wrap.
80 feet of 24-inch Reflectix insulation board
2 dozen turn button fasteners, with grommets
Putting it together:
1. Cutting the tarp down to size.
My trailer measures 8’ x 26’ plus the tongue, which holds the house battery and 2 propane tanks. I figured I might want the tarps to wrap around those as well, so I estimated a
length of 80 feet, just to have some wiggle room. I cut the tarp into 5 strips measuring 3’ x 20’. To do this, I had to open it up outside. There was snow on the ground at the
time, so the tarp stayed fairly clean. I had my son stand on it to help hold it down and help fold up each piece as we went. We also used rocks to help hold the tarp down as I
2. Sewing on the bubble wrap.
The bubble wrap was only 12” wide, so I had to sew 3 tiers onto each strip of tarp. This was the most tedious part of the project. I was also concerned that it would be hard on
my sewing machine, but it did fine. I had to clean the tarp dust out frequently and had to be careful not to catch the presser foot on the bubble wrap, but otherwise, it was
straight seams and easing the bulk through the machine.
3. Black paint.
After sewing on all the bubble wrap, the next step was to paint the outside of the skirting black. This is to absorb more sun and help retain the heat around the trailer. It is very
windy where we usually are, so I had to wait for a still day to get the paint to stick to the tarps instead of floating away.
We first tried attaching the tarp with velcro, but the wind made short work of that. We also found the addition of Reflectix insulation to be a major factor in keeping the temps under the trailer more stable. First, we stand the Reflectix around the perimeter of the trailer. Over that goes the portable trailer skirt.
I looked at what other people were doing with trailer skirts and liked the idea of attaching it with turn buttons. Amazon had them listed so I ordered 2 dozen and my son-in-law helped me to install them. I put the grommets on my tarp and attached it to the trailer turn buttons. It stayed on perfectly, but I now discovered that I needed to seal up the loose ends. This was a much better use of the velcro and keeps the wind from whipping the skirt up and blowing the Reflectix away.
Finally, around all this, we place our heavy tent weights, our extra sewer tank, and propane tank just for extra insurance in case the wind blows. If the temps dip below zero or stay below 30F for several days we still have to break out the heat lamps, but the skirting is doing its job and helping us stay warm and cozy.
And the best part about the Portable Trailer Skirt is that it comes off easy, rolls right up (both the skirt and the Reflectix), and stows away in the back of the truck or in the basement when it’s not needed.
