CapriRacer says "commercial grade" tire which IMO is different than Maxxis or BFG advertising a tire for "commercial use" or "commercial hwy use".
Just a point on axle choice from the trailer manufacture.
Some RV trailers came with optional upgraded (example) 7k axles in place of OEM 6k/5.2k axles. However the trailer makers tire choice is still limited to the OEM 6k/5.2k axle so a load range E at 3042 is still satifies the 571 FMVSS requirements.
I always order my equipment trailers with upgraded axles for better braking performance. Many Rvers have reported upgrading axle size for that reason. Those big upgraded 7k axles and a 3042 E tire reliability are a haulers delight.
