I was there last year. My primary concern was getting blown around in heavy winds in my 30 ft F53.
I took the road test which included weighing my coach on all 4 wheels for the first time. Just getting the right tire pressures helped a lot.
I had new sway bars installed which really helped with the wind problem. I spent a couple of weeks traveling Oregon and paying attention to the new handling. I decided to go back and get the shock work they had recommended done too.
On the trip home it was like a totally different coach, winds didn't both me, it took curves much better. Had to start watching my speed which I hadn't before. The handling of the coach was a built in speed limit, now I have to keep my eyes on the dial.
I spent a lot of money but it was like night and day, the new coach is a dream to drive.
With Henderson they will do the road test and give you a list of things you could do, I ended up doing most but not all. You can focus on what your main problem is and they can tell you what fixes will give you the best bang for the buck.
They have free hookups so you can stay the night at the shop, there are also some nice RV and State parks in the area.
