What kinds of tanks are they running? Where and how much as well? I'm thinking that once I got rid of the gas tank, I could mount a couple of 10 gallon forklift tanks where the gas tank used to be. How tough are they going to be to fill up under the 4runner like that? I'm trying to convence my dad that propane is the way to go on these engines and he's not buying it all that well. He thinks the HP will go down and I've read where you can gain some.
