When we first started looking for a larger trailer to replace our AirStream one of the things that interested us was the outside kitchen and 4-5 slides. We also were very concerned with resale value, and great construction. Arctic Fox, made by Northwood manufacturing - is a very over looked brand for most of us down south, it is more popular in the northern territory and Canada as the construction and the insulation is just incredible, very well made and thought out units, lots of great reviews, and good resale value. They also happen to have exactly what you are looking for in both 5th wheel and travel trailer. As a side note - I don't have any affiliation with the company in any aspect. But I sure researched that company and trailer brand to exhaustion. I can even give you a few names of dealers that will give you great prices if you are interested. In the end we decided on something a little nicer and went with the DRV - but hey who buys the cheapest trailer they can afford?
You can also call them and speak directly to the factory - they will do a order for you and place the front living room in most of the floor-plans, the out side kitchen setup can also be added in most cases as a option.
