My brother works at a United trailer dealer. Some of the advise he gave me being he see trailers of all makes and sizes is to get bigger than what you think you want. He also said regardless which brand I choose to make sure the suspension is torsion, not leaf spring. Also avoid lower end trailers because the use sub par materiel as far as the thickness of the wall beams, ceiling bows, tongue tubing size and the spacing between the bows and rail. I shopped around and ended purchasing one from his dealer. I end up ordering a tandem axle 7 1/2 x 14, (wish I went 4 more feet longer) with an extra 1' ceiling to make it 7'. Needed the ramp for easy loading and unloading. The ramp is rated for 3000 bls. Side panels are rivet-less and a transition flap so when your hand carting machines in and out your wheels don't fall into the gap between the ramp and trailer floor. Trailer has come in use more than just for pinballs, also make free storage for over flow in between pin shows. Good luck with what ever you purchase.
