I'm tackling my motorhome mileage at the moment - it dropped from 10mpg to 5 sometime last year....$60 to get to a regatta sounds like nothing!
yeah, that was my point. The Element wasn't very happy at 70 mph. Uphill it spent a lot of time in overdrive, so I just set the cruise in the 60-65 range. Engine turns dropped significantly.
On the other hand, I spent 3 nights at the Marriott, $532! To me, that's a lot! If my wife was with me I'd feel differently, but for one guy to flop?! I won't do that again!
Back in the day, I had a friend who just showed up, sailed, drank a lot and slept on a boat, any boat! Right out in the open! Maybe I'll. . .naw!
