We have decided that seeing the many wonderful places in the US will be our next adventure and we had planned to tent camp as we traveled way out west from Florida. We had even purchased a Springbar tent(our son is so happy that we won't be needing this tent). Now we have learned about teardrops and specifically Camp-Inn and this seems like the perfect way to go. We think the 550 ultra will be our choice but we are in the early stages of our figuring this out. We hope to be meeting many of you and hearing of your adventures.
