Attached are a couple of pics of my LRA 38 gal. tank.
Absolutely no regrets, it is hands down one of the best mods for my use of the truck. We do a lot of solo multiday trips with no set agenda, so the extra fuel provides a lot of peace of mind and extended range when exploring . As far as hard core wheeling with it, it I think that it is not the limiting factor on what trails you can handle or where you can go, the 2.5 " lift and 33's on my truck, for instance, are more of a limiting factor clearance- wise than the tank. I have never hit it (knock on wood), and we typically run Cruise Moab 6-7 level trails.. Metal Masher, Kane Creek, Steel Bender ,Poison Spider, etc.
The tank itself fits great, is a straightforward install, and comes with all parts and pieces needed. And as a plus, if you do go with an LRA tank, Ward and Georg at Cruiser Bros are great guys and big time supporters of our community.
I originally had a Long Ranger TA 39 auxiliary tank for several years before moving to the LRA. It was not the answer for me because it was hard to fill and a bit of a pain to transfer from it to the stock tank. The final "nail in the coffin" for it was going to an in-tank pump for the 2FE.
If you want to try the auxiliary tank, try calling Classic Cruisers in Poncha Springs. I traded it to them in 2018, so it might still be around.
And of course, anything from Jason would be awesome.
Hope this helps your decision.
