At post 110 I changed my mind and decided I would build a buggy instead of the Wag. The Wag continues to wait for it's next build.

At post 187 I ordered up a GoatBuilt JHF chassis to hopefully speed this up. (edit: nope)

==================

I bought my Wagoneer in 1997. It was my first 4x4 and I bought it so that me and my friends could go camping and have room for our gear since we all drove econoboxes. That fall I ended up moving to Germany for 18 months and it went into storage.

When I got back I rebuilt the AMC 360 with the help of a friend, and we did enough maintenance on the rest to get it on the road. Over the next few years it got a 4" lift and went from 31s and then 35s when I put a 3" body lift. We did some wheeling with it and eventually I put it on 33 Stampers from my old Wrangler.

In around 2005 it was parked due to lack of time and using any spare time on my Wrangler. A few years later we stole the drive train for the TREC Wagoneer, and it has sat since.

Over the summer I got out of racing, bought a RZR and drug this back in the shop. I'm thinking I want to get it back on the road and trails.

What I wrote on irate4x4. I don't think I need to modify the rig, but just take a different approach.

Takeaways in hindsight, we should have wheeled easy day 1 and got checked in and shaken down the rigs. That way we could have grabbed the key and been on the rocks as early as possible. We checked in and BS'd with staff and got instructions so we put first tire on Mammoth at 11am; which only left 5 hours before you should be off rocks and headed back.

The other thing would be to move to having spotters more quickly. I banged my way through junkyard and wasted time getting stuck, calling someone over, pulling cable to get unturtled, and then moving along. When whiterhino was outside helping to spot lines and adjust as it didn't work out, I made more progress later in the day than when treating it like the Rausch rock creek. I think 2 rigs spotting back and forth through sections would keep it moving. There's area you can just drive, but some it's pick your poison for what you have to get through.

Great to hear the rig is working as planned. Do you feel not having a ton of seat time is a big factor as well? I know every time that I go out, I push it harder and harder as I learn more of the capabilities my rig has and to be less afraid lol.



What the heck happened now!? Hopefully not a trans issue this time.

I'm feeling pretty comfortable in the seat of the buggy. It's a lot lower COG than anything I've wheeled, so that helps a ton. As Jim said, it's just a tough trail and I don't think we took it seriously enough to be able to make it through.

I believe 2 single seaters have completed, one without winching and one winched. Both had dedicated spotters. So it ain't no joke. A 2-seater rock bouncer made it about 1/2 way and then cooked his transmission. I made it just short of the 1000' mark and drove off the trail, was just out of time for the day.

Been getting random shop time lately, and I've been a bit scattered. I'm hoping to get back on track with the break I have from work.

Exterior panels are tabbed out. Still have to do the footwells, that is what I am working on today.

The remote hydroboost showed up. I have a spot I hope to put it between the seat and fuel cell, but first I'll make the firewall and figure out if I can fit it there.

What a miserable job. Painting tube sucks.

I told the sandblaster I was just going to hit it with rustoleum from a cheap HF spray gun. He recommended I hit it with rusty metal primer and then top coat. He also recommended to have a couple of spray cans available so that after I cleaned the gun and found spots I missed that I could easily cover it up. Was a great tip, because as I blew it off and tacked it this morning I hit any spots I missed. There were maybe a half dozen that needed some help. I'll do the same with the semi-gloss black.
