I am getting close to putting my floor on my trailer and my side walls up. I will have 12 inch storage area under my cabin (Like the Crowswing build). Since I will have the storage area as my air gap for insulation I am not building a flooring deck (ie frame, foam board ect..) My floor will be an exterior grade 3\4 piece of plywood. I plan on sealing it with "the mix" and then bed liner spray both sides of the floor.
I am seeking advice on how to secure the side wall to the floor.
1. Spray the entire floor with bed liner. Then use butyl tape where the middle wall meets the floor and then fasten it with a kreg jig
2. Spray the floor with bed liner but tape off the 1 inch area (with blue painters tape) where the middle wall meets the floor. Then remove the tape and use tight bond III instead of tape, then use a kreg jig to fasten it to the floor.
I guess I am looking for the best way to secure the side wall to the floor and provide a seal. My concern is with the bed liner being rough/bumpy not getting a good seal
Any other thoughts or suggestions are welcome.
Thanks
Wayne
