I have a nice 21'+ shop built, super heavy duty deck over trailer. Built in 1982 with american steel. 7k Dexter mobile home axles converted to 8 lug hubs, custom beveled tail to sit flat on the ground so even small cars can easily drive right up. Axles can be locked in 2 different spots depending on how the load is sitting. Rough cut lumber on deck, very thick. Electric jack. Led lights, etc. Needs a little to here and there, but it just made two trips to colorado and back, hubs stayed cool even on 100°+ days. Clean title in my name
