Enclosed Trailer Questions

6,000lb axles and 16" tires is the way to go in the long run. Best to have more capacity than you end up using. I also agree with more length than you think you need. 26-28' should cover your needs. It did mine when I was doing a lot of traveling and it served as a well equipped garage as well with counters, tool storage, oil, filters, spare parts, jack, stands, battery charger, etc. storage. My trailer also has a outside access generator and outlets on the inside and outside. If your trailer has the standard latches on the side doors, add the truck-style swing arms (or whatever they are called) so they actual cover the standard latches and add the extra security of a padlock. Of course, the more you haul, the bigger your truck needs to be, which in this case would be a 3/4 ton minimum.
