I recently purchased a M127a1c trailer and M197a1 dolly from the great guys down at the Idaho Motor Pool . I had just purchased my 1995 M35A3 in Boise and needed a trailer to pull home (450mi). (should have bought a M109 while I was there and have had them deck load it on the flatbed - ah hindsight!).
Once I got it home and finished with the truck upgrades and paint I tackled the trailer. Pulled the bed, ground the rust off, primed & painted, re-wired both the 12v & 24v systems (16/4 outdoor rated cables (2) for 24v system and 16/3 outdoor rated cable for the marker and 12v systems) and removed the landing gear and spare tire carrier. (spare to be mounted on back of trailer using 12v winch, swing arm and tire basket. the whole underneath area that can get storage boxes will get them along w/ a 200 gal fuel tank and transfer system).
I then installed the new insulated floor ( see post pg? 32 of show your trailers). The sub floor is 3/8 cdx plywood - stained with watco dark oak and sealed with 3 coats of Thompson's Water Seal. This was followed up by using 2x3 firing for joists and filled the gaps with 1" rigid foam, R5, then topped w/ 1/2" poly foam boards w/ foil top. The whole thing was capped by 3/4" cdx plywood with the outside sill plate pre-screwed to the decking before it was laid down. I left an access hole up front to get to the main wiring harness and air brake connections.
All said and done there is a 3/16" gap between the deck and outer trailer frame, to be recessed shimmed w/ 3/16" plexiglass shims and black caulk - will provide excellent drip rail and support. (before you ask - Im only using the plexi because i have a bunch of scrap out in the shop).
Tomorrow I'll set up the framing and will sheet the outside w/ 3/8"cdx covered by builders wrap and t-111 paneling stained dark oak. The roof will probably be shingles over 2 off set layers of 3/8"cdx with builders felt for a sandwiched core.
Enough for now, Ill post updates as it progresses.
