Hi, Guys! Suggestions / thoughts - Please?
We had our first trip with 3 - 4 nights in 20-25 degree overnight temps ............. and experienced somewhat a cold floor. And I admit - still learning the ropes of setting the TT heat for over-night ..... ;o) We have decided to add a heated mattress pad. And tighten up the hatch doors.
So, in looking at the bottom of chassis and I only see the tank area covered with Coroplast...? The balance of the undercarriage is just open frame to the weather cover under the actual hard subfloor. So - I'm thinking of 'laterally' adding treated 2x4s with (ledgers) in between the frame channels to hold the solid rigid foam insulation panels; and then cover the bottom of the chassis frame with Coroplast, just like the tank area. All tight and dry from critters and road wet.
Thoughts, please? Many Tks, D

Sounds like a good idea. Give Artic Fox a call and see if they have any negatives to the idea. I don't see any.

I can't think of any reason not to do it, but I'd probably use 1x material rather than 2x (just for weight). I don't know if it would make much difference, though, since it's still unheated space, correct? Once the underside gets cold, I think it's going to stay cold.

Yes but the floor will be easier to heat.

Skip the pressure treated lumber as it weighs a lot and if you must use a wood cedar is a lot lighter and rot resistant I once covered a cargo trailer and just used some construction adhesive and some screws with fender washers that would not drew through the floor and I never had a problem I didn't even use that many screws

Thanks everyone ! All very great ideas and I'll certainly tune (1x and cedar) my project accordingly! That's why the RV Brain Trust Forums are so valuable................ I'll take a pix as I roll-out the project. Best, Doyle

My OutdoorsRV TT is covered end to end and I thought the Arctic Foxes were also. I would call Northwood and ask.

I just bought a Nash 23D, love it and have spent the winter in the cold camping, down to 19 degrees at Prineville State Park. Only the tanks are covered, the front half is not. I have thought about adding some insulation and covering. Has anyone done this yet?

Can you weld 1in or 1.5in angle iron between the frame rails instead of using wood. Be nice to avoid rot.....

I have a northwood Nash 25r and it does not have the hard underbelly however it is insulated with about 1.5 inches of insulation and then the black fabric. We have routenly camped into the low 20's with no issues. I still want to add the hard covering though to help avoid damage to the fabric.

When I do it in was going to use angle iron and then throw some block foam insulation just for good measure.

if you get around to it post up some pictures!
