I had a Coleman Mach I Power Saver installed on my truck camper today. It comes with a 2 year warranty and an offer to extend that to years 3,4,& 5 for $90. Do most of you do that?
Extended warranties are generally a bad idea...if you don't expect something to last just don't buy it..most items which fail either do so soon, and are covered by any warranty, or last well past any warranty.
