There is only two of us in our OFF-ROAD POPUP setup so we just put a 3-inch memory foam topper on the front bed where we sleep. This is the best place for us since it has the trailer front deck underneath us to keep two and four legged creature from sneaking in on us...
We also use the 2inch by 2inch foam strips you find at LOWES for sealing the window on the house window air conditioner installs. They fill in the air gaps around the tent ends just great.
We also put down stick-on carpet squares under both bed ends and on the trailer floor. This worked great for making the floors not so cold in the morning but I didn't think about all of the leaves and other woods things that keep being brought into the trailer...
My trailer also has a hugh air gap between the where the pull out beds meets up with the trailer front and rear ends. You can look out both of these area and see daylight. I also installed a different rubber seal here to solve this problem. This also allowed insects to come in at night when they could see our lights on from inside the trailer.
I also added 9x12 tarps covers over both tent beds ends which looks pretty good when folded into place using stretch ropes etc... This protects our tent bed fabric from UV and darkens up the inside of the trailer big time...
We got one of these folding steps (AMAZON) to put at the bottom of our two steps arrangement. You can really stomp of these without doing any damage to keep from tracking in leaves and other trash when camping in the woods...
Try camping out in your back yard for a few times and see what you really need to have with you when camping off the power grid... Lot easier to go to WALMART and LOWES from your house then finding them when 30 miles back into the woods somewhere...
