Enclosed Car Trailer Buying Help!

Look for someone upgrading to a big-rig and selling their setup cheap...24 ft min...28 or 30' best...don't think I'd go longer than 30' with a bumper pull. I bought a 30 foot bumper pull that I tow behind a F-250 Diesel...I think the brand is Timberwolf (I'm away from home now) and it's awesome. You'll always want more room. Mine is flat in the front and has stainless steel work bench and cabinets, lights, winch, side and floor tiedown...$6K years ago...not sure what they go for now. Guy put a F-150 in there and bent some of the metal underneath...good thing he had the big beefy axels which were fine. Metel was straightened and reinforced....I've towed this baby across the country at max GVW 12,500 and it rides GREAT! Good Luck!
