While anything is possible, this sounds like a bad idea to me. The possibility of unseen leaks that could start a fire or explosion is a chance I wouldn't take. Also, in the event of an accident or rollover, the danger is amplified for you and your passengers. The cost may only be $300 but it could cost you your life as well. Good luck.

They have special valves made for this called roll over valve but they all say for diesel fuel only I am not sure why besides the combustible risk

In my opinion, just carrying 20 gallons in the bed is dangerous. If I needed more range that bad, I would spring for the larger tank.

The larger tank is great just I have affordability issues right now for that it costs 1500

I think I am going to make a custom tank to go where my spare tire used to be at and I will make a spout so I can fill it up through my truck bed i can fit a 30 inch tire in that spot so at least I can make a 25 gallon tank fit their or bigger

And how do you plan to transfer to the main tank?

I will buy and use the same kit that u would buy for a diesel transfer tank I will have a small pump hooked up to a switch and it will be hooked up to the hose that connects the tank to the fill up tube on the side of my truck

Check with the tank companys. See what they recommend. I’m putting a 46 gal direct replacement tank in the next couple of weeks. I’ll let you know haw that goes.
