I tried to search the forums and found a lot of references but no images. Any suggestions?
thanks, bill b.
What I'm doing is:
0) remove inner skins at rear of trailer, rear belly pan, banana wrap trim, banana wraps if needed.
2) remove all bolts holding C channel to frame
2) remove storage compartment door support from under plywood
3) drill out rivets holding rear hold down plate to C channel
4) replace rusty steel hold down plate with formed stainless steel one, with added row of rivet holes (standard seam spacing) across the top
5) add aluminum doubler behind skin and down over rear cross member to prevent further water intrusion.
6) replace damaged floor
7) use a couple of temporary pop rivets to locate rear hold down plate hard against C channel
8) drill holes through new plywood floor into C channel
from underneath through existing holes in rear crossmember. You'll add some holes in C channel, since plywood hold down bolt tops were flush w/ top of plywood.
Caulk heavily between plywood and skin w/ Vulkem where it crosses frame members.
9) lift both ends of frame w/ jacks to bring rear
crossmember up against plywood & C channel.
10) replace bolts with stainless steel bolts w/ self locking nuts - use square pieces of 1.5" square 1/8" aluminum plate to fit down inside C channel as additional washers to spread load. Original small bolts were #12 - use 1/4" hex head instead.
11) From inside, drill out through prepunched holes in rear holddown plate, through douple and original skin starting at ends. Add Clecos to hold things in place. Rivet once holes are drilled.
12) drill out holes in rear flange of C channel from inside, rivet from outside through C channel, rear hold down plate, doubler and skin.
13) remove jacks
14) Add caulk where needed, replace trim.
15) Fabricate new storage compartment lid.
16) replace interior skins
17) fill screw holes and epoxy floors ( 2 coats), paint w/ polyurethane paint.
I'll try and take some pictures tomorrow.
