I'd be pretty tempted to go for it, but make sure you have a trusted mechanic give it a very thorough once-(or twice)-over.
I know you didn't want to start a debate on this, but it's inevitable, so here goes... generally speaking you should buy a car that fits 90% of your needs. For example, I have a 4 door sedan that is great for everything except driving in the snow. It snows once in a while here (mid-atlantic region), and when it does, I'll either stay home or suffer through 15mph in the slow lane. I could use the excuse of oh, hey, I need an all wheel drive monster because it tends to snow in the winters... but then I'm over-buying, and I've got too much car.
It might be worth it for you to check out a gas efficient, cheap, minivan/wagon/big sedan that'll fit MOST (not all) of your needs... and then the once or twice per year you need to go camping, maybe rent the suburban from Enterprise for 80 bucks a day. Just food for thought!
