Yes, it all depends on where you want to go. RV'ing is not suitable if you want to go visit a big city. If you want to go to NYC, Boston, or SF for example, a car trip or fly-and-drive works out much better.
I still remember in our first ever RV trip driving through the LA metro area in a Friday night. The traffic on the freeway drove me insane. Would never again go through that.
But up in Montana, Wyoming, etc..., let alone the Yukon and Alaska, RV'ing is just beautiful. My wife is hooked.
I heard AK is nutso when summer comes around. But who would want to visit AK in the winter?
Also heard of Harvest Host or something like that where you can sometimes stay at vineyards and such for free.
It sounds like an awesome daydream. I've been working with my dad to try and find him a 37' fifth wheel. Some of them are super nice, but I hear even the brand new ones come with build and quality issues that will have you making repairs year one.
We spent $45,000 just on a 2500 HD to pull the RV, still haven't found the RV yet but that is looking like around $50,000 for the one that DF wants to buy.
So basically $95,000 before we hit the road and oh we need to buy a fifth wheel hitch and get that installed. I'm sure there are cheaper ways to do it.
You figure $100k / 5 years = $20k/year, then add in Fuel Costs, Upgrades like Solar and TPS, auto-level system, bigger wet tanks (for boondocking), five lithium ion batteries (to power that solar so you have hot water), generator (for when the sun don't shine) then a mail service that scans in your personal mail from the Postal Service, proper healthcare that will work in many different states... yeah this is 'aikin to the BOAT mantra = Bust Out Another Thousand.
I've also read some of the RV parks have limits on how old the RV can be, sort of like an association where there are rules...I hate rules.
I landed on a youtube channel Keep Your Daydream if you watch every season, front to back you will have a really good idea of the life of a full-time RVer.
I've heard of horror stories where people get harassed, etc. I suppose that all could happen in a suburban neighborhood as well though.
Mobile Mechanics will become your friend...and even those are hard to find...supposedly.
I remember when FEMA dropped off a travel trailer to my cousin down in Mississippi after Katrina wiped there tiny little town off the map. After a year of him living in there (by himself) that trailer was absolutely destroyed. He was happy to give it back to FEMA.
