uh uh, without Pete's consent.... the future purchase of SnapPads is on hold for me until further notice
Pete's advice is noteworthy.
They are heavy and caused the jacks to drift down during storage and they reduce ground clearance.
Heavy is a concern, I wonder what those 10" units weigh each? I really worry about any potential impact to Jacks due to weight when in use, or storage. I do tend to drive my RV like SUV; so ground clearance is bigger than what one might think. I have already lost my PET doggy bracket next to step that was made for tying up pets near the door. It got hit & bent up pretty bad by a cone that I ran over.
The more I think about it, I have never parked on grass expecting to put Jacks down. If it were wet, or rain in the forecast, I wouldn't even think about it. I do have my wooden blocks I made and proud of, but I have only used when I needed to adjust the height related to unlevel solid surface or to put under raised tires.
My Custom made SnapFree Pads
Truth be told, if rain is in the forecast we bring our slide in. No special reason other than I don't want to have to pull it in and it is wet ( not knowing when I can put it back out to dry and not mildew, I also may worry a tad about the wind blowing or ripping the slide topper).
This may be one of those things that I buy when I have a specific problem I have or some convenience that I mayy need in the future.
