Insulation underneath

[bsmoke]

I'm at the point of subtracting from my build sheet. Today I decided, which means that tomorrow I could change my mind , to remove the spray on insulation from the underside of the trailer. I included the extra insulation in the walls but have questioned whether it was worth it below. I certainly will be camping at times when it gets near freezing but not likely to often. Thoughts?

LOL, you'll hit a nerve on that one kinda like the storage box skirmishes. Two camps and both are feverish.
I'm in the don't need the spray foam camp, the gain isn't worth the cost and PITA to work on the trailer. I like Ron's solution with the foam insulation panel mod later if you decide you want sub floor insulation.

I think you answered your own question. Unless you intend to camp below freezing for more than a night or two, I don't personally see the need. As has been stated, there are lots of differing opinions on the subject, and they are almost entirely related to where the owner lives or camps.

Aside from the "need" for, or functional use of, these insulation options...

• it is not practical to add insulation under the wall lining later, but
• you can spray the insulation on the bottom later

so if you do subtract the underside insulation option now, you can change your mind any time after receiving the trailer.

Pre Escape... with no insulation on the tanks we would dry camp if it was going to be freezing. Just make sure there are bathroom facilities where you camp.

If it's just cold for a few hours at night it's no big deal, they won't freeze.

The insulation also works well for the hot season: especially when towing on hot asphalt. The trailer stays substantially cooler.
