Exactly. I know people that just bought SUV's. Why? Because it is 10-15K cheaper than buying a new car. That buys a LOT of gas even at $3 a gallon.
My suggestion would of course be a minivan with a towing package and WDH.
There is always the option of just slowing down. Best Speed for MPG? About 50 MPH
40-60 MPH - IF you believe in math
In addition:
- Drive at an even speed don't pass and if you do don't "floor it"
- Keep air filter clean
- Keep tires properly inflated
- Run synthetic oil
Saving 2 miles per gallon on a 1000 mile trip is BIG
Getting 10 MPG will cost you 100 gallons or $300
Getting 12 MPG will cost you 83 gallons or $250
You just saved $50 save another $50 on the way back
