I've had to remove about 1/3 of the underbelly cover from my 5er. It had 3 of pieces insulation around the tank. None that I could see anywhere else.
Has anyone added any additional insulation? What do you think?

If you are doing all of your camping in the desert southwest there, I wouldn't bother.
My new TT has the enclosed and heated underbelly. One of the reasons I bought it because I use a trailer when sometimes the daytime highs are in the low 20s for a couple of days in a row. When I was out this spring in it, I noticed a crack in the shower pan (had never been used before). I had a temporary patch on the crack to get me through a week long trip. I took off the access panel on the shower pan so I could monitor underneath for leaks. One night it was about 42 degrees overnight. At about 9:15 in the morning I stepped out of the shower and the heat cut on. Needless to say I dried very quickly. The air coming out from under the shower was ice cold.
When I get the trailer back from the dealer I am going to add insulation (extruded polystyrene) along the inside of the frame. In cold weather, that frame acts like a freezer. The corrugated plastic they use for a cover actually insulates better than you think because it has the dead air space inside of it.
