So we came across a 2008 KZ Inferno,we like the floor plan the stairs going to the loft is different. I tried to do some research but couldn't find much bad or good, I think the was more good than bad...
Although never owned one, I have always liked the Infernos. I think KZ makes a nice RV from what I've heard and like you, I've heard more good than bad.
If it checks out OK and you really like it, I wouldn't hesitate buying.
