Rent a Class C, rents are expensive but a lot cheaper than buying a length and floor plan on impulse and later deciding you want something else. Make sure that you both want a Class C and what brand, model, length and floor plan you both want. IMHO, a 3-5 year old 27 foot Class C with a rear bed hopefully with access on both sides has enough elbow room, storage and cabinet space for a couple and a dog. We have a 2004 Fleetwood Tioga 26Q, and have been satisfied with it. The Tioga/Jamboree 26Q model is no longer made but used ones are available. RV tires older than 5 years old may need replacing due to sidewall cracks/tendency to fail with damage to underside parts and possible loss of control.
