If I may, while I cannot offer any such coaches, I would highly re-think having a RV of that length w/ 6 people especially kids 10-15. May want to consider units more in the mid to upper 30 foot range just you have more elbow room. Perhaps you cannot go w/ a a larger unit, which is fine, but just offering a suggestion.
