Went to a group camp with about 70 people and took along my wife, granddaughter and her girl friend. We spent eight days there where it rained hard most every night and had beautiful days. The girls loved the seating instead of rocker recliners we had in another model. Lots of fishing, cook outs and shared meals in the RV. We had 10 in it for dinner one evening. With my wife and two high school seniors I stayed busy pulling the holding tank handles! I have had several previous trips of up to a week but this one put pressure on the RV. I am happy to report everything works perfectly. Water tight for sure after all the rain we had. Thanks, Grand Design!
