Over the weekend I had to perform a major service on our coach before putting her to bed for the next couple of months. My wife loves fall but I have come to hate it because it means the end of our RVing season for a few months. COME ON SPRING!!!!
Anyway, I changed the oil, oil filter, coolant filter, primary and secondary fuel filters along with both the serpentine belt and the A/C v-belt. I noticed that the serpentine belt tenstioner pulley sounded a bit dry so I replaced the tensioner. I am 100% sold on the Roadmaster S-Series chassis but I think they could have done a better job on the assembly line routing air lines. Over the past 6 years now of owning this coach I have re-routed and repaired multiple air lines going to air bags. I thought I had taken care of all of them a few years ago when I decided to look at ALL of them after repairing /replacing about the third one. I was wrong. They had routed the air lines for the two rearmost airbags on the front suspension right behind the shock. This not only pinched the air lines but they were ran around sharp edges of steel brackets. I decided to remove the shock and re-route them behind with some frame clamps to support the lines. I also greased all of the steering components along with the brake slack adjusters, s-cams and driveshaft slip joint/u-joints. I then serviced the wet hubs on the steer and tag axles.
While I was changing the oil I decided to add a Fumoto drain valve as they are much easier for draining oil. I installed one on out last coach but for some reason never got around to adding one on our Dynasty.
Here is the Fumoto valve after receiving it the other day.
Fumoto valve installed in the Cummins ISL oil pan after draining all 28 qts. of oil.
Oil filter and coolant filter replaced.
This is where I cannot for the life of me figure out why Roadmaster decided to mount the air dryer. It is just inside the left framerail slightly behind the left tag axle tire/wheel. I have found it much easier to service this desiccant cartridge by removing the tag axle tire/wheel on the left side and removing two of the bolts fastening the drier to the frame, swinging the assembly downward slightly, replacing the cartidge and then pivoting it back into place and resecuring it. When I say easy what I meas is less of a PITA, it is still far from easy. This alone took almost two hours to complete.

View with tire/wheel removed and the two top bolts removed allowing the dryer to pivot down slightly.
Cartidge removed. Be certain to clean the seating surface very good to prevent air leaks and also replace the o-ring with the new one supplied with the new desiccant cartidge.
New cartidge installed and the air dryer bolted back into its original position.
Torquing the tag wheel/tire back on. Torque is @ 475 ft/lbs.
New belt tensioner with new serpentine belt. I replaced the belts when we first purchased the coach back in 2007 but I thought it was time to replace them again. We have only put 40k miles in it in the past six seasons but I would much rather change these at home vs. on the side of the road.
New belts installed.

Toolcart. Holy cow it is amazing how many tools you can drag out for a simple job like replacing belts.
