So far I have been pretty lucky buying RV items over the internet.
We recently decided to replace our unused dinette for dual recliners. Looked great on the web site, good reviews from others, pushed the purchase button. $1450 later we have dual recliners with leg rests that hold in the up position only when fully reclined and material so thin that the dog punched holes in it the first time out (in 20 years of having leather couches and recliners, never had damage from our dogs - except for one dog that ate a couch, but that's another story!).
The backs of the recliner don't line up, the fold down center tray is at a 15 degree up angle, the foot rests swing off to the side, and on and on. Contacted the company and got "Unfortunately we do not have any adjustments in regards to the footrest locking in place when reclined. As for the material, we also do not make seat covers nor having any for these items".
So I guess the moral of the story is physically inspect before you buy. Anyone need an expensive boat anchor?
