Looking to ad a 35-75 gallon in bed fuel transfer tank.(not an auxiliary/plumbed in) What type should I get, aluminum, steel or poly? Aluminum scares be because it is so thin, and steel will rust.
I was thinking poly, should be less condensation problem?
Please only respond if you have or had one of these. What is your experience?

If a hammer can't fix it, you got yourself an electrical problem!

A lot of new construction boats are using poly or built in FRP fuel, water and black/gray tanks.

If you can get a correctly designed poly, it would be on lighter side like aluminum. The newest designs do expand in hot weather, contract in cooler weather. Some older designs will expand, not contract back.

Look up portable marine tanks to farther understand issues I'm talking about. Attwood has good info on their website. Where I work, we have portable transfer tanks to 50 gals for marine use. They have wheels, hose, nozzle, and need a foot pump, or small 12v battery, like a U1 size, to operate.

I've been using poly portable1-5 gal tanks for 30 years with no issues. I have no use in the past, or current future use. I would consider a poly before a steel. No aluminum tanks to my knowledge.

Considering it's going to be in the bed of the truck and subject to who-know-what impacts, sharp objects, etc., I wouldn't consider anything but aluminum. That's what mine is.

I have aluminum and it works fine. Inexpensive and good looking. Easy to fabricate with fill tubes and custom outlets plus custom dimensions. Square corners for maximum space utilization as opposed to poly. Not UV sensitive.

I have a 25 gallon Enduraplas transfer tank. It just sits in the bed next to the cab in front of the hitch. It works well. Has a built in 12 volt pump and standard gas station style fill nozzle.
I've had it about 5 years no problems. I paid 1/2 of what they are priced at now.
I power it with a 12 volt jump box.

I bought my steel tank to go in a new 1983 truck. The tank is now on it's third truck and doing fine. Next year will be 40 years on the tank.

Answer from someone who has run countless slip tanks both steel and aluminum.
Your fears about either material is 100% unfounded.
But you can get a plastic tank if you can’t get over the fear. However they are generally like the Fischer Price version of a time tested tool. In certain conditions I’m sure they’re fine and may offer a couple small discreet advantages like easily moveable or transferable between vehicles or locations. even though folks who probably profess to be safety conscious somehow have no issue with a large quantity of unsecured fuel container in the back of their truck.

And I’ll answer a question with a question. If a dedicated diesel tank for the truck, why the aversion to plumbing it in for hands free operation?

I have a 52 gallon aluminum, it does form condensation(western WA) so I would plan either don’t draw off the bottom and have a drain or have some kind of water separator. I went off the bottom into a water separator and then to a 30gph pump which is plumbed into the trucks filler neck. I have the pump hooked up to a mechanical 30 minute timer, one twist and about 15 gallons transfers.

40 Ga Aluminum in bed tank, probably 20K miles with zero issues, just install it as the manufacturer tells you (isolate aluminum from steel, allow the tank to move independently from the truck bed). I use a small fuel pump & nozzle to transfer the fuel, as I am to paranoid of warranty issues to alter factory tank neck.
