I upgraded from a 1990 Haulmark 24x8 to a United Super Hauler in August 2020. I bought it new and had it custom ordered. 28'x8.5' with 7'0" interior height, ST235/80R16 tires with 8 bolt lug, 5200# axles, driver side escape door, rear wing option, 1' extended tongue with electric jack, 4' door flap, generator door with compartment, deluxe "L" cabinet package with full locker, spare tire compartment, aluminum slide out step, prepped for A/C (Added an A/C unit myself later), raised coin floor, winch plate (added a winch later). I think the 7'0" interior height is a great upgrade. The 1990 Haulmark was a great trailer and I actually sold it to a friend who still uses it to this day. I was lucky enough to purchase this trailer before all the pricing totally skyrocketed. I was actually able to get the trailer for just under $20k, not sure what it would cost now. Trailer weighs 6385lbs empty.
