I decided to go with Ricks Tanks for my underbed gas tank. A friend of mine has used them for a couple of different builds. They are very nice quality tanks, but pricey. Unfortunately I had some problems with mine. I ordered it with a 2" bed fill neck, but they sent it with an 1-1/2" filler neck. Before returning it to Rick's I decided to test fit the tank and found out the mounting flanges hit my rear leaf spring perches. This would not allow the tank to go rearward enough, which caused the filler neck to be too close to the bed cross sill.
Rick's is a super company though and they want to do everything possible to make things right. Their customer service is personal and second to none. They scheduled a pick up and paid for the return of the tank. They put the rework at the front of their line so it would get completed ASAP. I am expecting it to be returned shortly.

I test fit the tank by putting it on top of my roller chest and lowering the truck down over it. It worked pretty well.
The mounting flange hit the leaf spring perch.
This did not allow the filler neck to move far enough toward the rear of the truck. The filler neck was too close to the bed cross sill.
