We have used XtraRide with great success over the years. Not mechanical and must get items repaired when they fail. Shops doing the work have been very pleased with how easy getting approval has generally been. It gives me great peace of mind and yes I understand the odds are I will not get my money out...... however, last RV had MAJOR issues that cost way more than what we paid for the extended "warranty." Some time involved but a signature and my $200 deductible paid the entire bill.
Regardless of whatever plan you choose. KNOW what is covered and what is excluded. Adjustments are not, failure of the components covered are. Our covers major engine components as well as coach systems. None that I aware of cover exterior surface failures(roofs and sides.)
All work MUST be PREapproved or they will deny.
Please understand what you are purchasing and follow their rules. Has worked out well for the RV loving non-mechanical driver. May none of us need it again!
