This is true for places like Curly's or the Badlands. Out west is another story. Moab, South Dakota, and especially Johnson Valley, it may take 2-3 hours round trip just to get a tool or part.My vote is keep it light, pack the spares in the tow rig, bring only basics. It's nice to have everything, but it sucks to have to dig it out for everyone all the time. Tow rigs are never far away.
I need to look into getting something more convenient for storage or I'm just ditching my hatch for a tailgate or something.
