my trailer is a 36' 90" x 90" inside 8.5" deep over the goose 3x5200 axles
i put new tires when i got it. I have never had a flat or tire wear. Never had bearing or brake problems. (knock on wood)
Triple axles tow nice. turn like shit. however, 98% of the time you are going straight.
I would say its worth a look. Whats the rear opening dimensions?
wish my roof was dome and not flat...
