My first camping rig, a 1994 Bayliner cuddy cabin, was the best investment I've ever made... in my family!!! I still have it today and it starts first time every time.
I spent more nights camping out on that boat, than I have on any of the trailers I've owned since. DW the baby and I would sleep in the cuddy, two of the girls on the back to back fold down seats, and one on the rear pop up sun pad. With a full enclosure, a porta potty and room to tote all our camping gear in the cuddy... it was my RV on the water.
