Guest wemit Posted July 15, 2019 Share Posted July 15, 2019 Quote You can use 3/4" plywood for the sides but 3/4" is way overkill for the bed bottom. I rebuilt my overhead and used 3/4" AC plywood for the sides and it added lots of strength and allowed for a stronger connection for the sidewall to main frame connection. For the bed surface, use plenty of framing and then lay down 1/4" ply over that. Lots of glue there makes it stronger, too. I also added 3/4" foam insulation between the framing, too.

ModocMade Posted July 16, 2019 Share Posted July 16, 2019 Thanks Wemit. Ill definitely use 3/4" on sides. For bed, ill need to research how to do those layers. The original bed seemed like it was 1/4" ply, then foam (in frame) then another 1/4" ply. Foam sandwich. Do you jave any pics or videos of how you did it?

Guest wemit Posted July 16, 2019 Share Posted July 16, 2019 Quote I have some photos of the cabover bunk repair. For materials, I just used 1 x 2 common lumber from Home Depot for the bunk framing since that's what was there before. The one thing I did different was to glue everything together with epoxy glue and then coat all the exposed wood with clear epoxy resin before laying down the 1/4" plywood. Hopefully the resin coat will keep any water that does get in again from getting into the wood. Not all of the wood was rotten so I used epoxy to glue the new wood to the old framing wood. So far it has held up. You can use 3/4" plywood for the sides but 3/4" is way overkill for the bed bottom.

ModocMade Posted July 16, 2019 Share Posted July 16, 2019 It looks like you did a larger 3/4" for the right wall, correct? Did you end up doing the whole window area? Quote Link to comment Share on other sites More sharing options...
Guest wemit Posted July 16, 2019 Share Posted July 16, 2019 Yes. the entire right wall is 3/4" AC plywood. The original wall had about 8 or 9 little pieces stapled together. Looked too weak for me. Quote Link to comment Share on other sites More sharing options...
ModocMade Posted July 26, 2019 Share Posted July 26, 2019 Admit did you glue the 1x2 to the fiberglass bunk bottom? Or is there wood sheet, the 1x2, then another 1/4" wood sheet? Quote Link to comment Share on other sites More sharing options...
Guest wemit Posted July 29, 2019 Share Posted July 29, 2019 Sorry for the late reply. I glued the 1x2 directly to the fiberglass over the cab. Quote Link to comment Share on other sites More sharing options...
