SMC Levelrs
Bruce Benson:
When we bought our coach, used, from Beaver Coach Sales, I was quite upset with the "ride" during the leveling process. To sooth my disdane BCS sent me across the street to Bend Equipment Repair. Richard put in flow restrictors, of his design, on each cylinder of the system. That settled it down from an "A ticket" ride to a "C ticket ride".
We do air up before we retract and air out before we extend.
One problem with using the manual retract is that the auto brings up two jacks at a time, thus relieving some of the frame twist. I suppose that the manual would have a little equalization in that the cylinder with the most load should retract first but the design is to do two at a time under normal conditions.
The cup in the ram is designed to keep the ram from slipping off of the axle pad and going through a tire. This was an improvement to the original design. A little grease might be good to stop some of the groaning, otherwise, I would not add anything in this cup.
One thing to watch for is the "up" switch on each jack getting stuck in the up position. The jacks are near impossible to visually check on the rear axle. If you think from the all up light that the jacks are all up and they are not you will probably have some very serious problems, let me leave it at that. These switches are brake light switches from trucks and should be available locally. Check them anytime you have a chance!
HWH will retro fit an air leveling system. Bend Equipment Repair is skilled at this change as is the HWH factory. If it really bothers you that is the best solution. I think seriously about it from time to time. The SMC system does provide a little more stability than the air. I would be hard pressed to go back to the ground jacks and all of the problems that come with that system. This one never makes holes or gets stuck and I think the coach is as or more stable than with the ground jacks.

Cost is about $6000 (includes active ride) for a non HWH set up and they had no venders that they trust to do a proper install. So it would entail a trip to Moscow, Iowa.
Bruce Benson:
HWH used to do it (last year) for much less without the active ride but I have no current knowledge. Bend Equipment Repair has done several but the price used to be near the 5k mark without the active ride. I can see why HWH wants to do the active ride themselves. Don't you just love Iowa?
The active ride sounds interesting. Seems like many of the installations are Country Coaches. Wish one of you guys would jump in there and do one and give us a report!

Edward Buker:
I assume that there are no available SMC controllers left. Anyone know? Who actually made these? Has anyone spoken with HWH to see if any of their hydraulic controllers might adapt? Any options out there that anyone knows of? Bruce, thank you for your post and providing some new insight into some of the system design and the HWH air option. It is an expensive upgrade and Iowa is not my favorite...
Dave Blystone:
i have the system also everybody should look at the BIG FOOT BY QUATRO they made my system and have some of the parts the have a shop in white pidgen MI and lakeland fla dave
