i would like to use the The Hopkins Graduated RV Levels, # HM08525 mentioned above, but the 2 sided tape will not stick to the "leather" in my cabin. i have read on this forum placing these in the cabin area saves have to walk back and forth to check the level by the fridge. i realize the level will very between what is seen in the cabin and what is actual by the fridge, but most of the time, it should be close enough. the question is, how does one get the 2 sided tape on levelers to stick to the "leather" in a newer Class C cabin?
