We are on year three with our 2003 Executive -
Replaced the Alternator.
Replaced the electronic control box for my AquaHot
Replaced the tension spring in the LR slide topper
Had the built-in water pressure regulator removed after it failed, which gave us MUCH better water flow in the coach, along with a good WATTS regulator.
Have had the entry door adjusted. A few Bin doors adjusted. All were getting difficult to open.
The Cruise Control needed attention as it would not turn on. Adjustment to the clock-spring in the smart wheel fixed that.
Puppy scratched the heck out of the tinting on one LR window, which we will likely address this coming season.
I voluntarily changed all the lighting to LED's so I will probably never have to replace another bulb.
That's it for us!
