Well, its Forest River. That means a crappy Lippert frame for sure. My travel buddy has a 2017 Forest River Surveyor that is about 25 ft and has had two spring hangers rip off the frame. Typical paved roads, nothing crazy.
The frame is not I beam or tubing, but rather looks like an I beam but is made of flat stock welded together to resemble an I beam. One of the spring hangers was welded on at a joint where the strips that make up the lower cap of the beam were butted together, a rather weak place to attach a spring hanger.
He bought it used. We discovered the drain hose for the Dometic fridge was never even pulled out and routed thru the outside vent. It was still coiled up and shoved behind the coils on the back of the fridge, right where Dometic puts them during manufacture.
The water heater is a Suburban gas/electric. Forest River bought the cheap models that have the electric switch on the outside of the water heater, no relay, no inside switch to control the electric element. You want hot water, run outside and open up the water heater, find the switch, hidden behind the gas valve, and switch it on, close it up and run back inside.
However, for $8000 you can afford to fix a fair amount of stuff. Hopefully no hidden water leaks.
