I've thought about this a bit. I would go to Pull-A-Part. Grab the tank and fittings from a Suburban. Take the opportunity to look at the pickup next to it and see if there are any other differences. Buy any other related parts I spot. Bolt my 44 gallon tank into my pickup.
The big question is if the tank would fit with my receiver.
