New.Flatbed. What should I be concerned/thinking about.

It may be moot now, but did you put any thought into a 3-point or 4-point diamond pivoting bed system? Sadly, if you do much off-roading, you may be in danger of pulling a truck camper apart, frame twist, by axle twist. There are ways to mitigate the problem, however. There are a couple gurus on Expedition Portal who have
BTDT with pivoting beds.
Another sure-fire way to locate your TC is by using camper guides: a quartet of triangle shaped metal stops (or facsimile) that reside in your bed to keep the TC in check. Some with campers that go all the way to the edge on flatbeds use 6 tabs to locate the camper on the bed. Two each side; two on the rear.
I have a buddie who has a MB unimog with the stock fold down side boards and an
Alaskan camper bolted to the bed. He keeps a lot of stuff along the sides. Cool rig.

Pickup beds are in the minority.

Mine has nothing but Fast Guns holding it on, never moves sideways.

rather than list the things i have done, ill add a link to my blog with the post of getting the camper on the flatbed.
i have now put thousands of miles on my set up. ranging from smooth highways to logging roads. rough enough roads that people are surprised i took my 2wd truck through it. ive driven it all year long in all weather conditions. if you have any more questions about my set up let me know. i am willing to share what i have done. you will find that the few of us that use a flatbed have very unique set ups even when compared to each other. you will also find that we dont care to go back to a regular bed. so with that in mind...here is the link:

Our budget build using a flatbed
The side cargo area is all framed in and has drop down doors. The diamond plate skins are next. These are a permenant set up, but could also be designed are removable. Camper is center located with several 3x3 angle and sets on 3/8 rubber mat. Tie downs go to C-channel at the front & rear of the bed (aka very strong).


The LH side has room for all the camping stuff, chairs, BBQ, cooler fits in there as well.


RH side has a tool box built in, rack for the N2 tank, and room for all the pit boxes and spare parts.

Hopefully you will have enough side bed clearance to allow the four legs to lift the TC up off the bed for loading etc... The open truck bed might be too wide for the support lifts...

Of course this would be no concern if this may be a more permanent install...

I would most definitely come up with additional storage drawers/doors etc.. That is my only downside for Truck Campers. I would lose my truck bed to bring along all the necessary support supplies making me always tow a utility trailer behind the truck.

The Aussie boys down under sure like the flat bed truck for alot of their setups...

I've used two pieces of angle, both have ends bent at an angle, for years. The angles have small drop pins (i.e. bolt) that corresponds with holes drilled in the bed. They just drop in.

Love Flatbeds and owned and used them since the 60s. Reality Check has the best suggestion. Just treat your camper, like a motorcycle and put a track in like you would the tires of a motorcycle, just wider to fit the width and length of the camper. I would put more height on the rails, side and front, to spread the contact more. Many have taken their flatbeds further, by installing tool boxes along side, on top and below the flatbed, as well as installing things you would not normally find on a Pickup. You can install DOT Propane tanks, under the bed as well as additional Potable and Waste tanks below. These additions will aid in lowering your Center of Gravity the fact that a Flatbed places a TC higher, above the rear axle, than a conventional pickup bed affords.

Also, attach your camper to the bed and not below it to the frame. The flatbed will torsionally move differently than the frame does, by design. Attaching your TC to the Frame will result in your TC being crushed between the two. Most Flat Beds are installed with compression springs to allow movement to occur between the bed and the frame. Which is good.

There a number of people here that have flatbeds, TC Life and btggraphix, immediately to mind and they are excellent in sharing what they know.

Have fun.

The camper did not come in contact with the bed rails before.

It does not need any support there now.

That space is free and clear for anything you may want to put there. Many people use the space for toolboxes to gain additional secure weatherproof storage.

I use them for keeping the sleds on when the bed is used as a sled deck. Each one keeps the inner ski in location (sleds have about a 38" wide stance). When I don't want them at all, they just lift out.

Tie down is the easiest part. I use the short fast guns (Derringers) straight to the bed rails.

And storage... always need more room.

I actually have airbags on the truck, but clearance is a good point.
