We have traveled when diesel was close to $4/gallon. I figured a 3,000 mile trip (8.5 miles/gallon) added $355 for the trip, if the fuel cost was $3/gallon. We can handle that on a 4 month trip to see our vast beautiful country. We stay longer at each RV park and cook at the RV more. I would re-figure our travel plans at $6/gallon but we would still go, just not so far. Good travels everyone.
