Tom, We use the AAA RV plus membership. We do not have any AAA insurance--just their membership. It cost us about $72 dollars a year and they will change a tire or tow you (up to 100 miles) to a facility for major repairs. When we had a travel trailer we had a blown tire and they were out in 15 minutes, changed it and we were back on the road. You also get the added benefit of their trip tiks and travel books/services. The membership money for us is pece of mind when we travel. It covers all your vehicles, not just your RV so if you have a flat on a car, or lose battery or whatever, they'll be there to help. Also gets you three gallons of gas if you run out. Just don't remind my DW of this one!!
What "cheap" air compressor do you use? Is it 120 volt or 12 volt? Does it handle air pressures adequate for PC tires?
