I had a bit of a chuckle when I read this, I bought my camper in 1996 and sold it in 2010, it had been used almost continuously in that time with maybe just a few summer months off down south, for maybe 3 or 4 times in that 14 years.
Longest period of time it was continuously set-up in the one campsite was for about 18 or 20 months in a caravan park when I got a job :'(
It's been down dirt roads, like the Gibb 3 x times and a few tracks/roads I forget the names of, that were just as bad or was that just as good
When I sold it the add just said "camper for sale" described it's make-up and size with the non-negotiable price, and that was all, the first guy to look at it took it away, he could see it had been 'off the tar roads' and I just told him it's history and showed him the work done on the springs and bearings, he lived about 3 Klm from me so we still see each other occasionally, and I know he loves it as much as I did.
