We also full-timed 16 years and traveled constantly. Not one regret. It's a great lifestyle.
You mentioned your wife is not onboard with the idea. First, don't force her into 'trying' it. You both have to want to do it from the beginning or it won't work.
You also stated you don't own a RV. Have you ever? Perhaps this is all too foreign for your wife - not knowing anything about RVing. You might try renting one for a weekend although it really is not the same thing as living in your own with your own belongings. Take her to a 'nice' RV park if she enjoys talking to people. If she likes more 'nature-type' areas, pick a good one for her first try. Pick an area that she'd enjoy.
Google 'blogs - full-time RVers' and a lot of good sites will come up. Have her read them to give her an idea of what full-timing is really about - and you too! It's definitely not for everyone.
Many folks full-time in a small RV but consider if you both like your own space - even though it would be a small one. Do you have hobbies? Your dog would take up room, too - just walking back and forth. Class C's can feel confining. Think about 'space' when you're looking for your RV. Class A's sit higher and have a bigger front window. It gives the feeling of space and openness. If you're looking for trailers a 5th wheel will give you a lot more storage space than a trailer and that's important for full-timing unless you're really minimalists. Lots to think about....good luck!
