Hi Oscar Mike and all,
Interesting article and rebuttal. I'm from the South Bend area and close to the RV Industry in Elkhart.
My thoughts on higher priced gas, will certainly slow down people traveling and spending money hurting the economy. Probably would need the vacation money to just go to work in their area, which would be a shame.
If fuel did get to the $10 level, it might be possible to run your RV to an area, live in a spot for a while or store it after you are done traveling, flying back (if cost effective) or drive back in a more efficient vehicle. Then return next season or when money permitted to continue on. Granted not the best way to go about things.
Hopefully a breakthough in technology will occur or some other answers and we won't be subjected to having fun doing what we like and should be able to do.
