Travis, thanks for that, I guess I would still check the load bearing cap. of whatever set you use. again thanks Regards Ray
I made mine with gravity rollers from those conveyor at UPS and Mail package handling outfits. Angles hold the rollers under the plywood tool deck, and the whole thing rolls on the bed of the truck. It's only about three inches high, I pull it out a couple feet at a barn to have a work bench. I can unload and load it in a couple of minutes, using a pair of saw horses, and the truck is empty. I have about a half ton on it. Cost a couple hundred bucks.
Steve Marshall, From growing up a garage door installer's son, I have not seen any door rails that will hold the kind of weight most slide out beds are carrying. But I could be wrong. It would sure be cheaper of those kind of rails would work.
Dang my beds six and half feet. Got all the materials and a working brief worked up. Will start on it next weekend
Sunny Cochran Ga. The plan is to mount the rails to the truck bed and use the wheels mounted to angle iron frame to which I will mount a floor of ply. The paper work at TSC states the wheel sets are rated for 450lb ea. I am not a kitchen sink kinda guy so I figure it should work. I am going to run the rail out on the tailgate too to carry some of the weight. I will keep two foot in the bed plus and eighteen inches on the tailgate means I will have no more than four feet unsupported. If I load gas bottles, shoe rack and anvil(70lb THM) as far back as practicably possible I should be ok. If it works for the year I have planned I will then invest in the real deal and a new truck to match. The reason for this is the four bucks a gal diesel and cost of maintaining a dually just to haul a 6x5 trailer. Its an experiment if it doesn't work I will drop back and punt!
Steve, I wouldn't use overhead garage door rail or rollers, I agree with Shane, although I did not grow up a door installers son, the mention of them was for the engineering point of view, a way to visualize. Bill Adams roller suggestion sounds very good and if he could give a description ,if not a pic, then you may find that you are miles ahead before you start. As would Smitty and others who have shown interest, good luck. Regards Ray Steele
