I like metal floors to a point. They can get slick at times, but usually never need replacing.

I really like torflex suspension. I've got a single axle 3500# I built & it tows like a dream,, empty or at near capacity. An x boss had a 10,000# tandem w/torflex & it performed the same. It is nearly 30 years old now & goin strong.

The Rolex IMO? A tilt bed Alumatrailer w/torflex suspension. $$$$. Built for life & never needing a paint job.

I borrowed an open center car hauler once that I really liked but that's all it was good for. Not like you could use it to haul dirt, gravel, or mulch...... But that might be a good thing wink
