Recommendations for 1990's model 22' Class C RV

There were some models with a rear 'U' shape lounge/booth
The table could be removed an placed low, all the cushions, would be rearranged for sleeping

Problem is, there is usually a water tank or heater, water heater etc.. under those seats, makes it hard to remove them and install desk and chair

Sprinter van office conversions are popular and not creepy
But way more money than you are think about
