'99 Tahoe - Expedition Build!

[HenryJ]

No, not a 2-gallon transfer tank, but a full size, 26-gallon 2-door Tahoe tank between the framerails! Then have a low-amp high-volume pump to transfer the fuel into the main tank.

You might find some ideas in my rig: BLT Offroad Avalanche

I found the Ford F150 tank fits really well and orients the filler neck in the right position. At 18 gallons It doesn't drop down as low as the other tanks that I checked.

The stock fuel pump works just fine for transferring fuel.
I use a Dakota Digital gauge that reads out in gallons. the transfer switch and an indicator LED right below it.

Even in a worst case fuel mileage scenario, I have a 600 mile range

I would love to do an offroad trip with another rig...I'm always solo!!!

I feel your pain. Most of my trips are solo too.
I have been fortunate to visit Moab twice. I met a friend from Kentucky and one from Brazil to do the White Rim Trail. Good times. My wise friend from Brazil had been there five times and said that was not enough. I agree.
We will return. I set no limit on the number of times...

I like that, even better, though I don't know if your filler door has more space behind it, I'll have to look. With my stock 30 (29.5) gallon tank and the extra 26 gallon tank, I'll have a total of 56 gallons, and at an average 16 (mostly highway) I'm looking at a range of 896 miles. That'll be nice.

Mine has a combined capacity of 49 gallons. I can get as high as 18 mpg at times. The would be over 900 miles. I don't like to run under 1/4 in the main tank since the fuel is the cooling and lubrication for the fuel pump. I feel very comfortable filling at 400-600 miles. The nice part is being able to choose when you want to fill. I have been able to wait past a weekend price hike. It is painful to the wallet when it comes time to fill up, but the time between those sure helps.

great pics and videos, makes me really want to get out again. I hate not having everything on my truck now since i got the other suburban and havent switched everything over yet.

I have to ask, how much does the extra tank lower the SUV?

I would assume not much, but then you know what they say when you assume

that seems a much better option than say 5 jerry cans

Not much, considering I have Monroe self-leveling shocks in the back

Gm rigs have pretty good rake to begin with. The extra 120# levels them out a little. I do have airbags too though.

I loved my blue suburban and loved the torque of the 454 but the mpg was killing us on long trips. I had been looking for like 2 years to find a good diesel suburban, their damn near impossible to find around here. Its a 94 k2500 with the 6.5td and the 4l80e. The nice thing is its basically exactly like my last one same tranny, same body style, same rear end, etc.. but with the engine i wanted and 4.10 gears. I stripped everything off my blue one bumper, winch, lights, rack, all interrior stuff, etc.. and luckily since this one is the same body style everything will just be able to switch over. Im just going to probably make a new bumper for this one and sell my other one, just because i think i can make some improvements to the design this time.
