Daily Driver, Go Where I Want To Build

Do we know how that works with all the TJ bits under there? I have a friend trying to do that now to get out to 100ish in a TJ and I'm not confident it can be done.
I’m not sure, It’s all just speculation. If it can’t get to 100 then it’s not worth the trouble. These are the dimensions. I’ll compare it to to my stock tank if i get some time today.

I thought we just went through all of this with Josh's tank issues, no?
No, he was looking at the 19 or 20 gallon dimensions. At least from what I saw. The 15 gallon is the newer alien tank that replaced the 11 gallon they used to have. Supposedly allowing same amount of stretch, but who knows

Well, I gave them a list of questions to ask in a pointed manner so we'll see what comes back.
 
You've already spent enough time off camber that you know you don't want a higher center of gravity. That and those channels will fill up with dirt, dust, sand and be miserable to clean out. The sand bits land, the aluminum flexes, and then the sand works down in and gets wedged so you have to chisel it out. That is a 100% street driven storage that will never work well where it gets dirty.

That and the second time you need to dig something out of the front you will absolutely despise that it doesn't lift up.
Good point on the rails filling with crap. I've had to deal with that on larger, more open rails.

I'll look more closely at the numbers tonight. I think the 15 gallon is about an inch shorter than the 19.5 I was considering. It might get just over 5" of stretch past what the Savvy GTS allows if you do all the little tricks to get there.

If I recall, a decent summary of why I didn't want to do it is in my final posts in the disaster thread linked above. It's a lot of work to get what you get. This includes a steel skid because I couldn't get past GR's use of aluminum right there.

If it doesn’t do what we want then it doesn’t work

Looks like it is fairly different. This is the tank you asked about.

This is the Alien. Looks like you’ll get 2” more stretch if the spring pads are the limiter but the Diff has a lot more room with the alien. I don’t know which would hit first

Looking at your thread about the 19.5 gallon tank, I see at the end you clarified that the spring pads and diff would hit at roughly the same time. If the alien tank is only 2” further back at the spring pads, and the ext tank allows about 4.5” of stretch, then the alien tank is only good for about 6.5”. Pretty far from their 9” figure, although maybe that’s feasible in a coilover application.

My hope is to stretch it to 101 with just a rear stretch so that if I want to move to 37s one day, I can achieve the rest of the stretch needed by moving the front axle forward. But we will see.

I cannot imagine using that that storage setup with a soft top or a hard top. It looks clean and good in photos but even for just hiking/camping use it will be a pain even if it did not have the dirt related issues you mention.

I saw two rigs in person a while ago, one LJ with a pull out Tuffy setup and one TJ with a full bed (ie no rear seats) Tuffy enclosure setup that tilts up (photos below). Both guys were happy when they installed them, and both have sold their Tuffy stuff after 6mo-1y when they realized it was more pain than what it looked like.

How bad would it be to cheat the spring pads forward a inch and a half or two?

Assuming doing so is beneficial, that just adds to the amount of work to arrive at what you get for the final product. In my case, it took less than that for me to decide to want to build my own with fewer, more acceptable compromises and greater benefits.

You might get 3" out of the front with massive amounts of tweaking and squeaking shit by other shit, doubtful unless you want to move the steering gear which I will never do.

What I do know is that with an axle that you can run 37's on around here, 104" of wheelbase in a TJ, there is no off the shelf tank that I've seen that will work under the back of the rig. I believe you could build a custom version that sneaks a pair of sumps forward on each side over the axle tubes with a center cut out for the diff if you get very creative though. Given that we notch the tub crossmember that the rear seatbelt bolts to for the joint bodies at full stuff, that only leaves you the height from the top of the axle tube to the top of the joints for sump height. In the below pic of 37's at 104, note that the back of the tire is past the rear of the tub by a couple of inches. That leaves you a very small footprint for a center mounted fuel pump option.

I still think this is the most practical solution by far. This solves basically every gripe I have about each option. I just know nothing about building gas tanks. Which is why I’m excited to watch Josh
