jimh425, the furniture in the rear of a Toy hauler really doesn't add to any stability. I can't say I've seen issues where the door makes it any less stable, assuming you don't buy the super light types. I have seen more issues, lately, where ramp doors don't hold up to the weight of the toys being loaded. But that is not that common either.
I believe that a solid toy hauler built 10 years ago that has been used a fair amount will still be solid today, if it was taken care of or it will show warning signs. Things like doors being out of alignment, soft floors, etc.
You've been around long enough I'm sure you know about doing a detailed PDI before you buy.
