Hoping to get some ideas for durable, cold weather skirt

I went as cheap as possible a few years ago on mine using the thinnest chipboard I could find.

I first cut a 2x4 into ~6" pieces and then screwed them in to the underside of my trailer along the edge. They were inset slightly so that the chipboard would be flush with the outside edge of my trailer.

I was at a gravel space so I dug down a couple inches along the edge of the trailer. Then I attached 1" styrofoam insulation to the chipboard and set it in the 'ditch' to hold the bottom in place, and the top was screwed into the 2x4s mounted to the underside of the trailer.

I cut small access doors with a hinge to get to my drain valves.

Holding tanks have UltraHeat stick on tank heater pads.

Used this for almost 2yrs living in my trailer. Survived good winds, and -20° temperatures without freezing issues.

Personally I wouldn't overthink this nor put any more $$ into it than absolutely necessary. I simply used cheap sheets of chip board as a skirt for our TrailCruiser hybrid - worked just fine. :B





If I were to do this again I'd use Reflectix sheeting, perhaps supported with 1"x2" framing. Put a light bulb or two within that enclosed area and it's amazing how much heat can be trapped.

Hi Brettmm92,

Vinyl will freeze in extreme cold. Then, if you need to remove it, it may well crack, leaving you with no decent skirt.

I was thinking some water resistant, mold proof, thicker vinyl (I'm assuming marine vinyl would work) with some snaps epoxied to the camper. But I was wondering if anyone has any experience or advice about it?

Thanks ahead of time!

I've been pondering on this for several years now, should I want to skirt my trailer. My choice would be concrete curing blankets.

Should I feel sorry for the guy when he comes back on and looks at some of his skirt help? :)

Wool or a synthetic blend?

See allot of old farm houses up here still using Hay. Two inch foam board and plastic also.

Except for the mice it attracts.
If your wanting something temporary a roll of heavy duty visqueen, some 2x4s and a roll of duct tape. 90% of the deal is stopping or at least slowing the air movement under the RV. Adding a couple of drop lights and your underside should be toasty warm in all but the most extreme cold.
