Planning a 440+6 tow vehicle, need a plan

on the pickups. have had a whole herd of them, yes the power wagon in even a 1/2 ton s stiff. right now I hacve a 3500 95 cummins ext cab 2 x 2 , good ride down highway, will kill your back on roughish road. also have 1500 2 x2 81 slant, rides great even on rough road. I have had several 3/4 tons all 2 wd ( any 4 wd will be rough ( to me), .... 3/4 tons are good to pull the correct weight trailer, my choice for sure. I have used a couple 1/2 tons to pull 18 ft bumper pull car trailer, with usually b body. it will pull it, suspension is adequate, ya better have good trailer brakes if need to stop quick, the 1 ton I have hasn't had a working brake control in it in years. BUT, if that 24 ft gooseneck was loaded and I had to stop quick, it would NOT!
personally, I hate any bumper pull trailer, period. if I was to get an older rv trailer I would look for a smaller one, unless just going local shorter trips. they sit high off the ground ( higher center of gravilty),, poor balance for what I have noticed, and if wind hit it on the sides! don't know!!?
all modern gooseneck horse/LS trailers use " rubber ride" drop axles axles, much better ride than springs. I wonder if the people than restore the old airstreams etc, change out the axles?
