I have a Sea Ray 270 Sundancer with a trailer, though I keep it in a covered slip at a marina.
Some problems using it to "camp" in:
1. the air conditioner will only work when the boat is in the water.
2. the fresh water tank is only 24 gallons
3. the black water tank is only 24 gallons
4. sinks and shower discharge directly overboard
5. a fiberglass hull is even less insulated against cold/heat than a travel trailer
6. my black tank has a macerator, but I need to be out in open water to use it. Pumping the black tank out onto the ground is not a good thing. I suppose I might be able to come up with a way to connect a hose to the overboard discharge, but that would require modifying the discharge fitting. Otherwise, the tank has to be pumped out using a vacuum.
7. my boat only has three 110 vac outlets and two 12 vdc outlets.
8. the refrigerator is tiny. Think dorm room size.
9. a boat that gets water inside it is no longer a boat, it is now a bath tub and will rot as quickly as any camper and cost a bunch more to fix. Camper canvas is nice, but is not water tight.
Some of these items are peculiar to my particular boat, but the majority of them apply to any fiberglass boat.
Much easier to simply have a boat to camp on the water and a travel trailer to camp at the campground.
