Because Phoenix Campers are custom, they are all a bit different.
Mine is 9 years old and is very utilitarian with not so great materials, fit and finish. Most of the problems, like the hand rail and lifting mechanism were just screwed into wall paneling rather than a wall stud. Fairy easy and straight forward fix is to bolt thru the wall with washers.
With any used RV, a thorough interior and exterior inspection should be done.
