Are you taking inventory with you? If yes, how about a fifth wheel toy hauler. That would give you a place to carry inventory amd still have a decent living area. A TT would be cheaper and you con usually tow with a lighter vehicle. A fifth wheel generally has more living space for a giver on the road foot print. Fivers also tend to tow better. But they also tend to cost more. A motor home would allow you to tow a inventory trailer or a small car. Depending on how many days a year your on the road larger trailers will give you more comfortable living. Floor plans? Your choice. All I can say on that is, go play house in each one you think you would like. Pretend your making a meal, doing paper work, laundry, taking a shower or bath. Do you each fit in the toilet room? Well gou get the picture. Same for storage. We did this with our last fiver and the one we picked served us well for over 11 years. Never a regret.
