I would echo Bubba1's comments. I have the 03 Neptune with a 300 Cummins. I have many options like 10 gals water heater 2000 watt inverter and 7.5 quite diesel generator to name a few. I bought mine 2 years ago for $50,00. with 21,000 miles on it.
End of the day it is only worth what someone is willing to pay. I enjoy ours and have never looked back in regret. This is my second HR class A and fit and finish is great. suspension problems can be fixed if you don't like the ride.
Buy 1 and enjoy it.
