Its not limiting us too much right now. I still tow with a gasser, and 87 octane here is around $3/gallon give or take.
So, we are already limited by the tow truck, because its a 2000 Ram and doesnt have the tow gear. I have to tow in drive, and when I am pulling the camper down the interstate at 60 plus MPH, i am turning over 3000 RPM and it is burning some gas!! Its just not fun towing like this for long distances. The fartherst I have gone is 4 hours, and I swore I wouldnt do it again with that truck.
So,I plan to get a diesel next year. I dont know if it will limit our travels, but I doubt it. We will only go so far on a normal weekend anyway. On long weekends we will go further, but that is only every once in a while, so I dont think it will deter us any.
