OK, I'll play too...
There are two kinds of people with slides,
Those that have had trouble and those that will.
:B
But seriously..... well almost:
Keeping in mind that among their other plusses and minus' slides add a lot of weight. Class C's, especially the larger ones, are vulnerable as they often have very little available payload {CCC, OCCC, ROCC etc.}. This gets worse with each additional slide.
Avoid floor plans where the galley appliances {frig, stove}, are in the slide itself. Look for units that have easily accessible manual over rides, awnings and large seals.
As always.... Opinions and YMMV.
