I worked at a WW dealer until 2007.
Yes they have some issues. Towards the end, their quality got real spotty, wiring issues, S/O leaks. The units with alum sides had leaks as the metal was frequently cut short (happened to the unit I owned).
Biggest issue, is WW understated weight- they are heavy. I weighed one that only had minimal stuff in it and it was within 200# of max GVW, no SxS, ATVs nothing in there.
