Can't help but notice that the whole thread is OPs from the Far North with their rough roads.
I have been on roads in Phoenix, Tucson and Vegas that are rougher than a lot of the roads in the "Far North"
Road from Edmonton to Yellowknife is better than I+95. Crossing the 49th does not take you back to the early 1900's. We even have overpasses high enough for motorhomes to get under, :B
We have a matching wooden one in the MH but still had the same problem. Had some left over venetian blind slats from a blind install in the S&B that almost matched. Glued them across the bottom edge and the sides of each shelf, Problem solved and they were thin enough that they did not interfere with closing the cabinet door.
Lets see how can we communicate ?
Phone.. no they listen:h
Mail.. no they read it:h
In person.. no they bug us:h
Email... no they read it:h
Oh the hell with it when we are all in jail together we will work out something :B
With multi viscosity oils they are at the lower viscosity when starting (or cold) but once your engine has reached operating temperature they run at the higher viscosity. The 30 oil will not cause any damage in the California climate.
If you don't believe it... google "multi viscosity oil"
Instead of spikes I bought four cheap 14" screw drivers and cut off the flat blade (could not find long Phillips) drive them in at an angle through the awning patio feet. Handles make them easy to get out and if you set your angles right the handles are close to the awning feet and do not stick out.
As some of you may recall I just went through a similar situation with my levelers. Received contact with azpete a member of this forum who is with HWH and is a travelling tech. He knows the systems inside out. He contacted me via PM so I was able to work back and forth. Not sure how to PM someone without a thread but I am sure some one will be able to tell you. Also if you go to hwhcorp.com you can find trouble shooting and system manuals. Takes a bit of searching in their site and you have to know your HWH system and chassis type.
