Yeah there's alot to consider here.
Poor RV insulation makes for hard times during the winter. Unless you get a winter pack of course. Or during the summer, AC running constantly.
Dumping your crap and waste every so often if you aren't connected to sewage main. Or if you're using public services, that can get old after awhile...
You'll need to be running a de-humidifier 24/7 (these things suck up power like crazy)
You'll need a power hook up
You'll need a water hook up, and hopefully your RV supports this, or you're going to be hauling huge buckets of water constantly for showers, the faucets, and general use.
With all the proper hook ups you are probably only going to find this at an RV park, which means camping costs - that alone can equal renting out a room. Then there's power bill, water, etc....
Like someone said, you may be better off renting a room and paying a buddy to store your bike.
It's all up to you.
Think about the effort you'd be putting forth living in an RV, and the costs associated with it. If it's still worth it, go for it.
I was in the same exact situation you are. I'm young and was considering just buying a toy hauler to live in, but when I found out everything that was working against me, it simply wasnt worth it for my situation. I ended up renting a room at a friends house and buying a large enclsoed trailer to work on bike in. I still look forward to an insulated larger attached garage, though.
Oh, and I don't know where you heard that you can pull 23,000 pounds with your truck, but you either read it wrong or someones giving you wrong info. NEW F-350 DUALLY Diesels would be extremely hard pressed to tow that much weight. Your motor MIGHT be able to tow that much, at low speeds, but the chassis and everything else with it is not rated at that for a number of reasons.
