Go for it. Worst case scenario it doesn't last a year and you cut the trip short. Go back home, regroup, revise the plan and resume the following year.
My wife and I have a similar plan. We have a home base so all travel will begin and end at that point.
We have a 53 foot boat so we will be travelling up and down the East coast and Caribbean and doing the Loop. Our boat isn't fast enough to do the loop in a single season so it will be a two maybe three season adventure. NJ North to NY up the Hudson River through the NY lock system into Lake Ontario. Then West through the Great Lakes. We will Travel as far as we can until winter holds us up. We will leave the boat where ever it is and go home for the winter. Resume the trip the following Spring. From Chicago, to the Mississippi River into the Gulf of Mexico. Around Florida and back up the East Coast.
During the down time. We will travel via a van equipped similar to a Sportsmobile. Generally it will look like a regular van not a camper. A camper seems a little cumbersome. The plan isn't so much to camp but be able to travel have all our clothes in drawers or hanging and not living out of a suitcase., be able to use the restroom without stopping, take a nap with out stopping, etc. We will stay in hotels/motels most of the time. But, if we find a great spot and want to stay a night or two we can. We will have basic cold food storage, water, a bed, toilet. Those trips would last a few weeks at a time.
