IBEX TRAILERS BY FORREST RIVER

FRIENDS ARE LOOKING AT AN IBEX AND I DO BELIEVE IT IS THE 23 RLDS. Anyone have one and how do you like it, what defects did it come with if any and how well did the dealer fix the defect. How is the construction and how well do you think it will stand up to travel. What are your thoughts about the construction materials and the build quality? I know there are some build problems and quality problems with the 19 QBS, little doors falling off and wall underslide out falling off etc. BUT how about this larger unit? How about is Forrest River standing behind this IBEX or is the same old story as most?
Thanks.
