The manufacturer's brochure says the Concord comes with enough seatbelts for the sleeping capacity - and each of the 2 bunks can sleep 2 tiny kids and the dinette sleeps 2 adults. The 2 adults, of course, are belted in at the front....

Thanks for the responses and pic.. keep em coming. Especially if anyone has a frame something like I want to do.
Kendas,
Do you have any pics without the plywood covering the watertank?
Thanks,
Jeff

From what I've seen in the new units, they use a frame made from angle iron. I know the wife looked into the specs for what kinda steel and how thick and such is legal here. I want to build a frame that goes around the water tank that you then bolt the seat belts too. There isn't much (read any) room behind the watertank to get belts bolted too. That is why I am thinking a frame that bolts to either side of the watertank. The first priority is definitely getting the kid (soon to be two) belted in good and tight.

What is the frame surrounding the watertank going to be bolted to?
It needs to be bolted directly to the MH frame itself.
1015, 1020 mild steel, 1/4", non-annealed. Hot or cold-rolled=no difference.
Go to a welding shop and snag some scrap cheap. They get the best steels, buying from a store (CDN Tire, Princess, etc), you'll get overpriced junk.
Cut with a grinding wheel to fit, drill and bolt.
Use BIG bolts.
Do not depend on wood for a sturdy frame.
Bolt seat belts to the floorpan or the vehicle frame itself.

The frame runs directly under the seat. Thinking about welding a plate to the frame that the bolt will go through. Probably going to get a professional to actually do the install. I might go see what the dealer wants for the frame. I assume since they can be found in the newer units, I may be able to find one prefabbed. Then again that might cost as much if not more than having a welding shop build it for me and install it. Another option would be to drill through and go through a plate (glorified huge washer) maybe 6"x6". My wife talked to the authorities and was told what gauge of metal and such was required.

Take a look at how seatbelts are fastened in most cars and trucks.
It's the secondary impact rather than the initial impact that causes injuries. Seatbelts are designed to prevent that secondary impact by keeping occupants secure following the initial impact.
Like helmets, seatbelts cannot prevent injury ... they serve primarily to reduce injury severity in an accident. Both do best in low-speed impacts - at higher speeds, they should use the same principle used in race car design ... absorb energy through sacrificial disintegration.
Using that principle, it's be okay for the seatbelts to "rip loose' in a high speed crash, as long as they slow the occupants significantly before letting go.
The force required to rip a 1/2" bolt, backed by a large diameter washer, through a piece of 3/4" plywood is very significant. Your 6" x 6" backing plate should be more than ample for the task.
BTW - most of the steel in light and medium duty truck frames is 3/16" thick ... the only place I'm using 1/4" steel is in the body brackets and that's only because the Energy Suspension universal mounts are designed for 1/4" thick material. (It's easier to use 1/4" stock rather than shim up for thinner stock.)
