Resize pictures, please, so we don't have to scroll side-to-side. I use 640 p as the size limit. Here's an app that will make a Forum sized image and it's easy to use:
Photoposting appAbout the holes: From the images,the two that are covered are probably the intake/outlet of a removed propane furnace. Any other holes may be for marker or running lights.
*Where to start to give you some good info?*
List a brief background as to your skills with electrical, plumbing, and carpentry. I won't tell a fella' how to catch sailfish if all you have is a cane pole. Also, a mission statement (what do you want to do with the trailer).
FWIW, I have gutted and restored a few travel trailers/campers. The link to my latest effort is in my signature line, "The Cowboy/Hilton". Photobucket has nerfed the images but the text is all still there. I can send you some images at request. It is a 22' travel trailer. I did all the work myself, spent $5K doing it, worked on it for 6 mos., mostly full-time but not breakneck speed.
I own more tools and power tools than the average guy. I also had some things in stock from my business, Residential Building Contractor. I'm real happy with the results. The Hilton is a go-anywhere-there-is pavement rig, in any weather. I spent a month installing new windows and insulating.
Let us know how you plan to proceed and we can throw some advice at ya'. Good luck!
