Yeah, I've used ratchet straps like that to lift my bike when replacing the front wheel. They are overkill for luggage purposes. =)
I like Arno straps for luggage. They don't take up any space and are only a couple of bucks. You can get them at camping stores like LeBaron.
Roc Straps for the win. I used them last year and they are fantastic; the elasticity prevents them from loosening and having gear fly off. Trust me, I used to use the other straps used by those riders posted above me and had my tent fly off the back of my bike. It will never happen with Roc straps.
I recently found myself with a desire to get a Ural ST but I don't think I could justify to myself spending extra money on what I see as a lower-tech and lower performance bike.
Currently I use whatever I can find, or at times I bring along a folding chair that is massive and I hate bringing it. I am looking at this from mec:

The downside is no backrest to chill out with in comfort at the end of the day, that doesn't concern me to much at the moment though. Its small portable and relatively cheap.
What are you guys using for camping chairs?
I'm looking at getting one for a trip on the Trans Labrador Highway but buying one at Mec for $80 had me staggering in price shock. I used to use a ten dollar folding camp chair from Canadian tire, but it's too heavy for this sort of trip.
