Uh, isn't that exactly what I said? One spare and multiple extra tubes. First flat, put on the spare b/c it's quick and easy. Additional flats, break 'em down and repair/replace the tubes.
I don't know a darn thing about chaining up axles, so I can't really speak to the original question, but wouldn't this solution be a lot simpler/cheaper/easier?
Spare tubes are great, but what do you do when you blow-out a sidewall? And don't tell me it doesn't happen, or that it's not likely. That's not the point. I'm just trying to provide for one more 'what-if' scenario and I don't see what it could hurt to have a couple of extra brackets bolted to my frame that I'll probably never need to use.
I would be really interested in hearing what you have planned for your M109 conversion. I could see living in the M109 for a couple of weeks at most, but a few years? You must have really come up with a interesting setup to be able to make use of all the available space in the back of the truck to be able to live it out of it for so long. Trust me, it may look big when empty, but once you start putting stuff in it, the space fills up fast.
Good luck on the project.
...I couldn't see myself living out of the truck full time. A couple weeks, maybe a month, yes. But it could get cramped pretty darn fast if living out of it for a very long time.
Your 109 conversion was one of the first I found, and it helped to convince me that I could turn a Deuce into what I was looking for. I've designed the floorplan (and everything else) with living in it (and working out of it) indefinitely in mind. The floorplan makes pretty good use of space and there is room for just about everything that I'm planning to take with me. Plus, I'll have a12ft enclosed trailer that I'm building out of that M353 trailer chassis in-tow. That's going to be a fully-outfitted workshop and toy-hauler.
I've spent the last few months collecting parts and planning and learning everything I could about motorhomes. I've built a lot of off-road vehicles, but I knew NOTHING about RV's or plumbing or any of that crap at the beginning of this year.
But I'm pretty happy with the way that this project is turning out.
I'll start a build-thread soon, but it's not much to look at yet. So far I've only got the interior cleaned-up, the sub-floor (3/4" plywood) laid down, the 1/2" PEX tubing for the radiant heating (yes, radiant heating) all routed-out and laid into the sub-floor, and the vinyl flooring installed (mostly).
Davis Cabinets is helping me build-out the interior, and I spent a week over there with them framing-out all the cabinetry. I'm going to finish installing the flooring and I'm going to paint the inside of the box this week, and then next week I'm going back over to Eugene to finish building/staining/installing the cabinets.
