Another Coachnet fan. Had them for years, used them three times including a $2200 flat bed, 350 mile "tow" in Alaska in '08. All done professionally, as promised and Coachnet kept in contact until completed.
I second the warning about AAA RV coverage - as you travel, coverage may well depend upon IF they provide RV service in that area.
Check the details - how far will they tow. Coachnet makes a service appointment for you and tows you to an appropriate facility. Hard to beat. Good Sam? - may be just as good but I have no desire to change from a proven provider. Good luck with the decision.
