Our 2004 Tioga 26Q Class C fits our basic age 80 needs/wants. It is actually 27 feet long, has no slides to leak or give problems. It has "most of the comforts" of home but does require care in backing into campsites, handling on twisty mountain roads, and has stock Ford E-450 drive train and suspension. The rear springs are stiff and give a harsh ride on cupped interstate highways, I'm looking into Koni "FSD" type rear RV shocks to help soften the ride. We have never towed a vehicle or felt a continued need for it, not wanting awkward parking and backing, etc. Will rent a car if ever really needed. Our rear queen bed is east/west type with access on right and bottom sides only. We use two sleeping bags zipped together so don't have to "make" beds.
The 26Q model was discontinued in 2008 ( I think). It has a large rear cargo area with mounted spare tire and wheel. More recent rigs may have more advanced electronics and comfort features.
You might look into Phoenix Cruiser and Lazy Daze Class C's for best build quality and support.
