Custom made for a 27' Baja $700. I have towed at 100 MPH (yes literally ). And it goes no where. If you will do alot of towing get custom made,, much less hassle. Yes Boatnuts cover was half the price, but it is 10 times the Bullzhit and looks like a ballon going down the highway. Great for storage and short trips though,,, and like he said, only 300 bucks. Depends on your situation. ( I am sure Paul will chime in about the office friendly that pulled me over on the way home from the Ozarks soon to prove the speed !!!! ) Love that Silverado 2500 !!!!
