We had a 2015 Chateau 31W with the same floor plan. We just sold it and of course took a loss. But it was a good MH. I upgraded the front and rear sway bars with Helwig, and upgraded to roadmaster steering stabilizer. It made a world of difference.
A few things I would like to have changed were, the cab seats to swivel around for use while camping, opt for the bunk over cab for storage space( entertainment option was in ours), recliners over jack knife sofa.
Think about towing a car, you had a vehicle with your 5th wheel but now you won't and renting is a pain at times specially if staying for a few weeks.
Never had any major issues with ours and the new owners still love it.
Just my 2 cents worth, good luck with your decision.
