What did you do to your Class A MH today???

I have been having a problem overheating while trying to climb the "Grapevine" in CA so I changed the hydraulic filter for the p/s and hydraulic fan hoping that more fluid will go to the fan. I had already replaced the priority valve and pressure relief valve as well as the t-stats. As I crawled underneath I noticed that both muffler brackets were broken and the only thing hlding up the muffler was the rear mud guard so I made new brackets. Finally I installed a new sliding plexiglass window in the screen door- I had broken it getting out of the mh one day.
