So far our plans only call for hauling our rig 200 miles to our summer site, then down to Goshen for the rally, and then back up north for the rest of the summer. We might toss in another trip down to Mammoth Caves, prior to the trip north. That's still under discussion. But for major road trips, we still use our timeshares and drive the 4-banger Chevy Equinox. We took it in November to Orlando and then over to Gulf Shores. Averages 30 mpg and plenty comfy.
I don't like rising fuel costs, either, but I won't let it stop me from enjoying myself. Flying and airfare, on the other hand, are another story. We used to do that a lot.
