Wholesale Warranties here as well. On my new coach the cost for a 7 year, 75K miles, plan was far less than what it would have cost for a three year plan on my 2005 coach, which would have only been good for 35K more miles.
Obviously, the older it is, the more risk. On the other hand, I had the dash A/C go out (had to replace the compressor, hoses, evaporator, and the whole ball of wax). The generator also went out, which is several thousand in replacement cost. Either of those repairs would have exceeded the cost of the premium for the three year plan.
Therefore, as with all insurance, peace of mind is not always the true benefit of the premium.
If you compare it to a Good Sams/Camping World extended warranty for similar coverage, it was very reasonable. CW will charge you at least twice as much, with far less coverage.
