I know several people with brand new rigs (within the last couple of years)...some of them high-end custom-ordered. All of them are different make/model. And yet, ALL of them have had or are having issues. Some folks we know have their 6-month old rig sitting at a dealership right now waiting for warranty repair on the inverter and electric awning motor.
I will not say that our 2005 unit is flawless or that the previous owners didn't have issues along the way. But each time I think about upgrading into a newer rig, I think about all my friends who are having problems.
