Overview of mods and contents:

Most other things EXCEPT the suspension were documented in this post, originally from the OS:

For the benefit of some of the new members who haven't been around while I've been building this project up, I thought I'd throw together a few pics as a summary of the projects I've done, many of them with design help from trailvoy members.

If it also serves as an inspiration with the summer meet and offroading season coming up for most of the NA continent, have at it!

Most of these mods have been discussed here, but I can understand folks not wanting to go back and read four years of archives to see my posting history. :D

Total inventory pics. Part 1

For some odd reason, I wasn't carrying my container of spare lamps when I did this series of pics after Moab. Didn't notice it until I was spreading everything out on the driveway. Also I carry a spare CV shaft underneath where the spare tire used to be. That's not pictured, either.

Otherwise, enjoy this stuff I've been collecting for camping trips starting in 1973, when I got out of college and started doing more outdoors things.
