Well I finally picked up my RED BIRD 2004 29WBLE.... Hitch weight 2200lbs Trailer 10000 not loaded yet clearance 7 inches from box rails clearance from cab lots of room ... Are these weights normal in that length .. Truck is 2500 HD duramax SB Thanks Dan
As you can see, I pull the same rig with my 04 Chevy D/A and have no problems. Never had a problem with the sides of the bed getting too close to rig. I do keep the rear fresh water tank full to counter the pin weight.
Hope that you have many hours of happy camping trips ahead of you.
