I'm considering the RDS 91 gal tank/toolbox that has a small area outside the toolbox but still under the lid for the fill neck. I'll do gravity feed but may do a small pump in there for other uses but probably not the full on transfer hose setup.

Check the measurements for sure before you buy, those big combo box/tanks can be too wide to fit down between those corner reinforcements in the bed.
Otherwise you would have to space it back 5 or 6 inches to avoid them, leaving a gap at the front of the bed.
The 60 gallon tank I used is super tight.

Right. It looks like all of RDS' tanks are 55" wide and I measure 58.5 at the narrowest.

That allows 3.5" for plumbing.

But, there are mounting tabs on each end of the tank too...

I'll just cut those off and duct tape it in. Maybe a bungy for safety.

I believe the posted dimensions include the tabs. But they're short enough to fit in the side space.

Just use a ratchet strap across it from the bed corner tie downs.
Of course the tank you are looking at is different than mine since it is one of the toolbox tanks.

I’m able to transfer about 5 gallons in a 10 minute pumping cycle while I’m going down the road. These pics are from when I installed it in my 2020 but it’s identical in my 2022.

That is a well thought out design. Due to the lower height of the tank a bed cover will work with no issues.

I too believe the 55" tank will fit. But you will need about 57" to 58" of clearance if you want to draw fuel from the lower drain plug area and use a shutoff valve. You could use an elbow at the drain and run it rearward to install a shutoff valve then down to gravity fill, I think someone here did that but it could have been in iRV2 or someplace else.

My RDS tank, when centered, leaves barley enough clearance for a shutoff valve. I think even if you push yours all the way toward the passenger side you may have just enough clearance.

Here is a photo of my RDS 50" wide 33 gallon. That's a custom box I made strapped to the top of the tank; since I have a Roll-n-Lock cover I had to improvise on the box.. On the right is my AirLift compressor. sorry - no good photo of the clearance on the left hand side.
