Cycler, we aren't quite there yet fulltiming but will share a little of how we got to where we are today after RVing extensively on many weeks extended trips in recent years, and doing the "assault" course back in the 90's and early 2000's when the kids were younger and we were working our tushes off to keep the wolf from the door so to speak.
Always had the dream to go FT when I hit fifty and hubby 57 = well sadly that's long gone due to youngest deciding to go late into University and completing end of this year, getting married next year and then "freedom 55 and 60's" are in clear view. Just like our goal was Australia for 3 months RVing when we hit our 25th wedding anniversary = didn't happen and we are a decade further on still not happened. That's the one thing that's become very evident to us and urgency has set in, "if" we don't just get on and do it NOW, when will we!
Initially the thought of ever giving up our SnB's just wasn't an option with me, but over time, and frustrations I've done a total 360 about turn, and can't wait to no longer own any real estate. Besides which "nothing" is forever!
Seeing what it is now costing with tripled and more to come increases in house insurance, exponential in our eyes property taxes, maintenance that takes these now achey bones and limbs longer and longer to do, I am with hubby now and happy to be "free" from RE ties and binds for a few months/years or who knows maybe decades. Just going to play it by ear, but know we like many say here "wish we'd done it long ago".
As for Fifth Wheel, C' Series, B Series, Trailer, A Class etc etc. It's a bit like trucks, you'll hear advocates for all depending on their nature = just like you have FORD supporters and GMC supporters. It truly is a personal choice and all you can read is several blogs/forums of folks in different types of RV's and sizes. For example GonewiththeWynns, prefer smaller 33ft A class diesel, and have had a gas engine lastly and initially started I believe with a small trailer (they are now starting sailboating but their site is a mine field of info). Wheelingit.us have the "Beast a large A Class, Technomadia converted a bus and have just done some major renos after a few years of owning as well others they phased in. Then there are a ton of folks that tend to stay sited for a while at each location so they prefer the roomy interior of a Fifth wheel.
Hubby and I started with a Fifth Wheel in the 90's and knowing no different loved it. In early 2000 bought an A class gas engine 37ft and it's still perfect for us all these years later. WHY? Well for "US" personally we like the extra storage in the bays, love being able to access the house items without having to go outside, love the easier press buttons inside set up, and generally we don't tend to stay in any one place for extended periods. We are travellers more than sit and stay folks, so to us "right now in time", it suits us perfectly. Yes hubby would love a diesel, but we are struggling to get our heads around the extra cost of purchase to say nothing for us not being mechanical of the extra costs for maintenance. Now that last comment someone else that's very mechanical hands on would warrant other reasons why a diesel is better than a gasser (so does my husband but it's the HP and engine stuff LOL).
We've seen many RV's with lifts on the back that have a motorcycle on them FWIW.
Anyway's one things for sure there's no hard and fast rules and no right or wrong way to RV. Good luck with your final decision. Maybe before committing you might want to rent two or three times different types to see what you feel when actually out in them? Just a thought.
