Regarding the one spare vs 2 issue:
on my 1st North america trip after shipping from Germany to Jacksonville and then driving to Palo Alto to store for the winter, we went to Baja. An aftermarket Koni shock froze up, broke in half and one half ate the inside sidewall of a very heavy duty 395/85R20 Michelin XZL. I had only one spare, which kind of psychologically crimped the rest of the Baja trip. In Tucson I found a "gov't take-off" XML, but it spontaneously blew out a sidewall in Saline Valley, Calif. So again no spare until Edmonton, Alberta where I bought 2 slightly used (>95%) XZLs. For my recent Australia adventure, I carried 2 unmounted spares on the roof plus one mounted on the back. I wouldn't have less.

Hi all, away for a bit at AA (Aussiespeak Anonymous). I read the forum a few years before joining and have found that Charlie's contributions are always well thought out, very detailed and, most importantly, based upon experience. "Let experience be your best teacher and you shall succeed". So with much thought about the 2 vs. 1 spares issue, I think that I am coming down on the side of 2, because of Charlie's tale but also due to the underlying logic of...'it is better to have them and not need them, then to need them and not have them'. Especially since we plan to defy the stereotypical U.S. rv'er's travel plan and actually and actively seek out asphalt -free trails. BLM lands, Forest Service, Army Corp of Engineers, etc. Besides, that ATW GW rear rack design is growing on me and it's incorporation still leaves plenty of options. Regards, Dean
