Inside storage/towing length

Ok , i have something simmiler with out the slide out or exterior kitchen. For 2 adults ( sleeping together) and 2 kids you will be fine. Your cabinite space will handle the food. Out door kitchen will handle the drinks. Inside fridge will hold a ton of stuff especially with a freezer your not used to. The pass through will hold chairs for all. Biggest problem will be the first year orginizing and making use of every available space for storage of clothing, and jackets etc. But it has 2 wardrobes up front. Your used to tents so you are used to taking less stuff. You will be fine. I went smaller with mine because i can go some places where the bigger campers can't. So some state parks etc. So size is all about how you look at it. Ots a nice camper and should be fine. It has plenty of weight capacity to load it up. If you plan meals etc , you can go for a while withlut having to stop to get food. We did 18 days in disney, and made all but like 6 meals in the camper. Never had to go buy food once. Good luck!
