First: I love the L322 and I really like what you are doing! And the TuffAnt wheels look wfc - way cool.
A couple of comments on what I read:
- Carrying a replacement front strut is impractical space wise and weight wise. And a trail swap, while without a doubt possible, is
not something I'd be excited about having to do. Rear air springs are not that bad, but still: if you revamp the air suspension the chances that you'll have a failure in the next 6-8 years are quite low (we have stats due to our customers). EAS issues are generally on old vehicles with poor maintenance. Parts prices have become quite bearable. Inspect and replace as necessary or just replace the struts, rear air bags and rear shocks and be done with it IMO. And have fun off-road with peace of mind. Just my 5cents.
- I have a 275/65 18 Maxxis MT in my spare wheel well. No air (no valve when forcing it in) and a bit of sweat. Tires of the same numerical size are all slightly bigger or smaller depending on the manufacturer or model, but I'm betting you'd be able to fit your spare. That said, I'm planning a swing away spare tire carrier for my L322 too
- While I am not completely objective on issues such as this, I believe my opinions are well founded. If you maintain your EAS, you very likely will not need an additional inflation system, and by clipping air lines to introduce additional inflation valves you are drastically increasing the number of potential failure points in your EAS. Every junction point is a potential leak source. Leave your airlines stock and, if you really feel the need, buy an IIDTool, use it to put your RR into build mode, and inflate each airbag manually to the height you want also using the IIDTool. The suspension will not release air and self level till you leave build mode.
- And last: did you really drill through your roof to add those rails? Front Runner really wanted you to do that? There are 6 M8 thread inserts under the roof rails stock. They will hold a lot. I have had a RTT and way too much poop on my rack on nasty washboards in the Sahara / Northern Africa, and through all sorts of terrain in Asia minor and Europe without issues. I am even less a fan of drilling through a virgin roof than clipping air lines. If it's necessary, then yes. But on the L322 it is not.
Not bashing anything, just constructive criticism
