@Ceili,
I repaired a boat with some fiberglas tape and epoxy sxhmear one yer(It was a speedy boat that I hammered into a rock on Fundy) We spent a night in a wee town N of ST Georges and l;et it dry. When we got going the damn fiberglas plug lasted so long that I actually sanded it down as a permamnent repair. Otherwise Ida had to punch it out. Body epoxy with no fiberglas depends on the shape of the hole and whatever stiff patching you put on the back. (SOme holes , like in a double hulled thingus ( are hard to get anything pother than screening behind and My fiberglas quick patch had more strength cause it covered itself over the hole (also about the size of an apple) and exceeded the hole dimension by severa;l inches.
In other words, Id do a fiberglas kit patch, its fairly easy, the entire kit ois available at a chandlers, and it holds like a rock (once its cured a day or so, Then, for you to sand it , prime it and then paint SDudley all over(I see a great big Dooright face on one side of the rig and a Canajun sympbol on the other. The best cartoons are those that are so big they slop over slightly on the roof and the front. Just get Doorites face near thedoor with eyes looking at the door.
Either that or the Stephen King Clown with pointy teeth. (Thatd be my choice, it keeps kids at bay) We had to replace the door on our Trillium too. I found that piano hinges worked great cauase you can really get some screw purchase on the big sheets of the hinges. It takes two people to fit em up.(I screwed up at first and we had to put in a whole sheet of fiberboard on the door.
ALSO, another little trick is to put that liquid wood hardener on the wood surfaces where you will be re screwing holes or tapping new ones. It holds great too.
If you have a frig on the brain (Get a DOMETIC) they have dealers all over and are pretty standard with parts. But since youre gonna put elec brakes and a new jack plug on, remember you can run the frig on the truck battery while driving and it cools er down really well, then when you get to your plot, just switch over to gas or camp electric (depending on what youre gonna set up)
We found that, with no heat system (just the stove heat) we could run the frig and do all the cooking for about 2 weeks on one bottle of gas.
*Now we use the 50 gallon LPN tanks and run everything off gas
