Yes there must be 20 to 30 different places up around Napanee that make trailers and hire amish workers. Jayco was started by an Amish family.

Large family Hmm. Then you may want to look into a brand called the Sportsman, Personally I do not like them as well as I do Jayco, actually alot less but they may have the bunk house you are in need of. I believe one of theirs that I looked at had two sets of bunks on both side and a kind of loft over the bunks I believe that it would sleep 6 children so if you have 3 or 4 then a couple could bring a friend. Camping goes easier if the kids have someone to occupy themselvs with besides mom, dad, grandma, grandpa. Not that I did not mind playing catch, badmitton, walks and awnsering all kinds of questions but there are times when I just want ot sit and watch the fire.

Good luck in your search.
