I'm kinda mad at Bob, cuz he was out of town (Boston turfgrass show) when I was in Casa Grande last week to visit. lol Not sure, but I think the B & B carrier rack is all steel??? We had ours made locally. Light weight and 'dual receivers' instead of one. The ramps & platform are aluminum. We also remove the spare tire from our 2500 HD pickup trucks. 300 gallon spray tank (usually only carry 75 - 150 gallons), 40 bags of fert, carrier rack w/T3000 = no prob. You can see pics of our racks here -- just search for dual receiver carrier racks. I've seen other guys fabricate theirs too. We hate pulling trailers, but I think most T3000 owners use trailers, cuz they often haul mowers too..
