How Much Weight Can Bed Sides Handle---Homemade Sled Deck

I would like to build a sled deck that rests totally on the bed sides of the truck. It would need to be 102" wide by 84" in length to be able to hold 5 motorcycles with a total weight of about 1200 lbs. I will be adding air bags to the rear axle for stability help.

I currently have a homemade ladder rack on the truck which I will either modify or start over. I want to make the new rack with just the headache portion and the 2x2 angle iron sides. Then the sled deck will slide up on top of the 2x2 angle, which is bolted onto the bed caps with 3-1/2" bolts, and bolt to the side rails. I think with the deck bolted to the rails I shouldn't have to worry about the bed sides tweaking.

Appreciate your thoughts/suggestions.

From an engineering standpoint, because there's so much "surface area" the weight is distributed upon, plus it's mostly in compression, I would think the 1200lbs wouldn't be a problem.

BUT,,,, what IS going to be a problem is where it's located...

You're drastically effecting the CG. That much weight, that high, and you've created a 70mph pendulum

I would have support legs that come down and tie into the frame where the bolts for the bed go. No extra holes in the bed and all the weight and load is transferred to the frame. That is a lot of weight that heigh up. Not to mention trying to get them up there when your done.

I agree with the legs under the middle, but you could also just get a utility trailer

I do not think 1200 lbs is an issue specially since the bed has vertical supports at the front and rear then the wheel wells

we have had lumber racks that support across the bed rails and have loaded thousands of LBS on them between 5/8 drywall and big ole beams

that being said when we pulled the racks and bed liners the bottom of the beds were deformed around the mounting bolts from all the weight LOL

just make sure the across the bed rail is rigid I have seen bedsides bow out due to racks spreading and no tailgate to hold it all together


the center of gravity is a worthy concern however no worse than a cab over or loaded lumber rack IMHO

they sell some cool toppers made for quads to sit on


ps bags mounted at the frame rails aired independently will help sway

351-The trailer will be a camper, hence the need for the sled deck. A toy hauler is too much $$$$ and I'm not sold on a 5th and a tag behind that.

zmann-I was thinking the same. I think I've had about 1000 lbs on my truck rack all on the drivers side! And some of those slide in campers are over 3k lbs( I know, they sit on the bed floor) but it is still a ton of weight. Friend of mine had a slide in around 2-2500 I think and said there was a huge diff in stability once he installed air bags.

I know it is going to be top heavy so I will have to adjust our speed accordingly. We travel only about 100 mi's to most of our destinations with very little Interstate so keeping the speed down won't offend too many.

Thanks for the replies.

you should add bars in the middle , car weighs about 1700 pounds , only about 5" of tubing goes into the bed holes , call me stupid but iv done 90 down the freeway with that up there , barley notice its there , this post was just to show having 1200 pounds up there wont hurt anything at all
