A PO removed the OEM tank and installed a gas grill tank fitting on the regulator. I have the OEM tank and need to re-install it in the Sequoia.
I don't have any of the mounting hardware.
Is there supposed to be anything under/on top of the plywood to span body framing members, or fender washers on the bottom or what?
Carriage bolts?
I can't tell anything from the CanyonLands, as a PO removed the OEM propane tank from it as well. I can cannibalize the regulator and any other gas plumbing stuff I need from it, but there are only 4 holes in the bottom of the compartment to hint at what was originally there.
If there is some kind of bracket/hardware above or below the plywood, pictures would be greatly appreciated.

Well,
I'm really glad it didn't say tomorrow morning.....
The propane tank is mounted with four each sets of hex head bolts down from the top. The only thing that is not just tank and plywood is a pair of straps that span the bolts where they come through. There is nothing spanning the floor frames in the area. I hope this answers your question, if it does not, I can try again. My coach is in a warm barn and I am out there frequently these days.
A short word of caution, if you go to upgrade the regulator to a two-stage, seriously consider your reasoning. I did. I also replaced the rubber line in GP. It has been a major PITA. There is barely room for the two-stage, and making up the hose connection down at the floor is another adventure because there is not room to get a wrench on the hex or the fitting that penetrates the plywood. My gas detector says I seem to have a leak there, but I can't make it blow bubbles.

That is OEM, there is plywood under it.
If your not comfortable with that, then put in bolt and nut wit washer and
use some blue Loc Tite.

Also do not forget to install the ground wire under the head of one of those bolts. Look at the picture on the previous posting and you will see the wire installed on the left leg.

One bolt. 2 flat washers 1 split washer, 1 nut per corner. When I removed the tank to paint I replaced it all with stainless due to tire kickup zone.

Update: Once I knew about the straps, I found a couple hiding in a dark corner of the CanyonLands propane compartment. Along with a correct regulator.
The tank is in and all loosely fitted and waiting for me to go to the hardware store for some bolts, nuts and washers, plus dig a roll of Teflon tape out of my plumbing supplies box to plumb it in tight.
In case anyone is interested, it is a bear getting the tank into the compartment of a 23'. Had to remove the fresh water fill tube to get an extra fraction of an inch in that direction, then finagling and literally prying in two different directions, a 2X4 at the bottom of the back and a 1X4 at the front halfway up the door.

Aham,
Sorry, I should have told you about that. I ended up bending the flange at the front of the door. I never have bent it back.

I have always used Yellow Teflon tape on natural and propane gas fittings because I have it. I do not know if it is required or just a recommendation. Teflon tape comes in 4 thicknesses and colors:
White - single density
Yellow - double density
Pink - triple density
Green - Quad density
