You are going to be spending a lot of time inside this camper (whatever you get). So get something you are completely comfortable with.
One thing that happens with any camper (of any size) is how fast they get cluttered up and then everything feels horribly claustrophobic. It will drive you nuts in a short while.
You can (and will) adapt to any size, style, or type of RV you get. But to be successful (and happy) your entire lifestyle and way of doing things has to change too, that is far different than living in a house or even an apartment.
Because of the shear size reduction, you can't bring it all with you. Extra stuff will either be sold off, given away, or put in permanent storage somewhere. You will down size EVERYTHING! Clothing to the amount of food you have available. Rotating Summer to Winter clothing may be a bit daunting when you don't have extra closet space any more. Stocking up on 6 different flavors of Ice Cream, keeping a week's supply of frozen meats, and a gallon of white and a gallon of chocolate mile, along with a variety of soft drinks and "adult beverages" in the refrigerator ... well ... it just won't happen.
You'll learn very quick to have less on hand, throw more away, shop more often, fix only what you can eat at that meal, no leftovers, and get everything for only a couple days in advance in the refrigerator.
You'll have to down-size the time you take showers, as a 6 gallon water heater will provide hot water for only about 7 minutes and then it has to heat up again. You'll have to down-size how much water you use, as your holding tanks will hold only so much water. If you are at a full hook-up site, this won't be so critical, but still you constantly have to monitor your water usage and the amount going into your tanks. Black water (toilet) tank needs to be filled before dumping it. Unlike a house where you flush every time and forge it. If you open the drain on your black tank, the tank will soon become a solid clogged mess. You are constantly aware of your water usage, your tanks, and hot water output.
Pots, pans, dishes, all are downsized. You'll need to learn to prepare a lot of meals in 2 pots, maybe an electric skillet for everything. You simply will not have space to bring along your current kitchen stock.
Practice now downsizing. Practice taking Navy showers and adapt the lifestyle now. Practice fixing your entire meal in a single, or at best, 2 pots or pans. Practice now, using only 4 plates, 4 spoons, 4 forks, a small assortment of cooking utinsils, and of course, no automatic dishwashers, and washing everything immediately after eating. Otherwise, dirty dishes become clutter, clutter, clutter very fast! And counter space is extremely limited in an RV... so...
So, pick what's most important: blenders, toasters, table top toaster-ovens, Drip coffee makers or Krueg? You won't have counter space for any of these, they have to stored somewhere. So, figure it out NOW what you actually use and get rid of the rest.
Your entire wold will be down-sized. Absolutely everything.
If you have a large enough living room, remove everything from the living room and tape off the floor with a box, 30 feet long, 8 feet wide. Put your bed inside that box, the television, and all your clothes, dishes, food, everything, and see how cramped and tight it gets .... very fast.
This is probably going to be your hardest adjustment, and what you really need to consider in your choice of RV for full timing.
When you really put this into perspective, it changes everything when you start serious looking. And if you've never experienced the RV lifestyle, you will be in for some pleasant shocks and surprises. That's why you really should practice the down-sizing now!
Yes... 6 gallons of hot water! Think about it!
