Removing the underbelly cover

Roy, I am looking to do the same thing you did. I want to mount my battery box on the back of the trailer to alleviate some of my excessive tongue weight. My under belly sheeting is broken into 4' sections with about 8 screws each (4 per side). So, it doesn't look too hard to do just wanted to make sure I wasn't going to get myself into any trouble. Plus, like you said Roy, it would be nice to know how everything is routed for future repairs / upgrades.

I took mine down once to route some 4AWG battery lines... Lots of self tapping screws for me... literally 100s of them haha...

After that I kinda of know now where things are located so the time time I needed to get inside I just took a few self tapping screws down. After the third time of needing to run battery cables I installed a 2-inch PVC line with easy access points between my 12VDC power distribution center and the battery switches locations..

Cutting a three side flap doesn't sound like a bad idea as well... I'm sure you could come up with a quick seal if you went this route...

I park my trailer right next to the woods here in CAMP BACKYARD so its pretty important for me to keep the whole underbelly material in place. Lots of field mice and squirrels here...

It can be a little bit of a hassle due to the caulking/sealant and expanding foam used.....plus the 100s of self-taping screws

BUT...if I was going to do soe rewiring I would remove it (with the help of a friend--------and their help to re-install)

Cutting three sided windows is a method used for limited access to repair.

I have taken mine off several times. The first time, I cut it into three sections so it was "easier" to reinstall. Still a pita. If what you need to do is in a localized area, cut a three-side flap and tape it back when you are finished. If you need access to the whole thing as I did, the only way is to remove it. Mine had spray foam around the plumbing penetrations. It's easy to spray it back when you are finished.

If I removed it I would reattach it afterword.

Seams like most people will cut a flap and then tape it closed when done.

I am fairly new to owning a travel trailer but i wouldnt beacuase that plastic sheeting is there to protect the underside of the trailer floor etc from rain dirt etc. but thats just my two cents unless you just make like a small small hole just to run the wire then glue or tape it back.Or just hit me the best way to me is go to walmart or advanced auto and buy that plastic round tude that is split along one side to put wires for cars and just run the wire in that ant attach it to the frame.
