Have you ever "camped" or overnighted in a boat?
It truly is an experience to avoid in a boat that size, in my opinion.
Its crowded, no head room, cluttered. Coolers, food, cooking....
Its either hot - but you have to have the boat closed up because of the bugs; or its cool and damp and you have no furnace.
Been there, done that.
Better off with a bow rider and take it to a beach or campground and pitch a tent.
Personally, I think the $6,000 price point puts you in bowrider territory.
And as said above, preferably aluminum.
Aluminum is lighter, so you can get by with a smaller outboard, which uses less gas, more forgiving, no rotten stringers, etc.
Remember, the trailer is just as important and expensive as the boat.
You could easily stick $600 - $1000 into a trailer to get it back in shape.
brakes, tires, bearings, axles, lights, brake actuator......
You can get some really nice boats for $6000 total, but not a 25' cruiser in my opinion.
Minimal service and maintenance on a bigger boat will be 5 times more than you imagine, and thats if nothing is broken.
Pretty common to take one in and get a $1500, then add on your survey costs, and safety equipment, insurance, etc, and you better have another $2500 to add to the $6000.
