Here are a few thing I learned from my experience.
When making reservations at campsites don't tell them you are a boat. For some reason telling them you are a boat gets them nervous. As they say, "It is better to ask for forgiveness rather than permission" . I have never been turned away and they usually love it when they see our "cute" boat. I did have a close call once, but they capitulated.
Carry an adapter for power. RV 30 amp plug is different than Marine 30 amp you can make and adapter, but I have found them pre-made. Also carry an adapter for standard 20 amp to 30 amp Marine.
Have a way of collecting gray water from the thru hull if you are using your sinks or carry a basin to catch the water in the sink. I made an adapter so I can drain right into the sewer connection or I can drain into a 5 gallon bucket.
I carried a 5,000 BTU window air conditioner and placed it in the opening to the cabin door at night with the canvas rolled down to the top of the AC. On those humid 80 degree nights we slept well. Carried it in the bed of the truck when not needed.
Carry an infrared thermometer and check tire temperature and hub temperatures at each stop. All temperatures should be running about the same. One way out of whack could be a problem.
I always use google maps on satellite view and examine the ramp I may be using for launching my boat. You can often see the dock situation and even how long the ramp is. I do the same for hotel reservations to make sure they have good entrance and exit access and parking. Always call in advance and ask about parking and tell them how long you are.
These are a few highlights from 35,000 miles of travel cross country and on the east and west coast. PM me if you want to pick my brain more and I can give you my phone number to chat as well.
