In the meantime, here is a post I published on a FB page several months ago, about going fulltime.
I've been reading a lot of posts from newcomers who have yet to actually try living in an RV and yet want to go full time.
May I suggest that newcomers try it out first? We rented a Class C from Cruise America, although there are many large RV dealers out there who rent out various types of RVs.
Take it out for a week and try living the lifestyle. After, make a note of what you liked and what you didn't like. Need more pantry space? Gotta have that walk around bed? One bathroom not gonna cut it? You can learn most of this stuff before sinking your savings into a unit you may end up not liking.
If you love camping at state and national parks, you probably don't want to get anything longer than 35' because that seems to be the cut off for most parks.
Like fancy resorts? Then know that many have the 10 year rule, meaning that if your rig is over ten years old, you will probably have to show pictures of your rig before they let you in.
Everyone's taste is different. What is a priority and deal breaker for me, may not be important to my neighbor. But you'll never know if you don't try it out.
Most RVs depreciate greatly as soon as you leave the lot. So, before you go upside down in an RV payment, please, please try it out and see what you like and what you don't like.
Please don't take this post as criticism. Think of it as a guide to getting started. We started with a 5th wheel.
After five years, we realized that we would be happier with a Class A. After realizing that a gas model wasn't for us, we traded up to a diesel. These changes cost us a lot of money.
Hopefully this post will save someone a ton of money.
