I don't think there will be any issues but will post up for scrutiny.
We bought this trailer at a local big box (Menards).
We will cut off the uprights, rails and ramp. Should we leave the floor?
The other questions are:
Trailer height - ground to bottom is 15". Sound OK? I think this is sufficient but will require me to add a hitch receiver to the truck to get a level trailer ride. The axle is mounted over the spring.
Floor mounting - As you can see in the pic below the trailer has an upright angle iron in an L shape. I'm sure this is more than workable and I've seen others use this configuration. Anything to watch for?
I plan to overlap that with the outside skin like the generic plans on the HF trailer and will build in an 1/8 rabbit along the bottom of the wall (laminated type) to account for it.
Front of trailer - Should we add angle irons from the corners forward? We'll have plenty of steel to do it after cutting the sides and rails off.
