Just like to add a few observations about RVing in Europe after 12 trips spanning 3 weeks to 12 months starting in 1967.
1) TC's are almost unheard of. The few you see are Tacoma sized trucks with small TC's. Your unit would be pretty high, with A/C unit, compared to even the largest class "A" units which are much smaller than their American cousins. This and the width including jacks could be problematic in the narrow streets of eropean towns and cities for driving and parking.
2) Since my first time in 1967 until our last time in 2017, there has been quite a change from tenting to hard side RV's including trailers, vans, class "A" and "C"'s with lots more campsites that supply AC power, dumpsites etc. Hardside RV's are everywhere so buying one that suits you would not be a problem.
3) A/C and generators are almost unheard of. 220V and 12 V fans are used exstensively when the weather is hot.
4) Because of the restriction of space in many areas and the price of fuel, European RV designers are pretty good at packing a lot of conveniences into small spaces and keeping the weight down, their units are fairly fuel efficient.
5) If you are planning to be in Europe for an extended period, during the cooler times of the year, southern Spain, Portugal, Italy, France, Morocco, Greece ,Turkey are all fairly warm in the day and cool at night, no A/C required. Plus there are many year round campgrounds in these areas. During the summer, northern Europe has very pleasant temperatures so as long as you have the time and are mobile, you can pick what ever weather you desire.
6) In 1991, when on a world tour, we bought a small, used class C near London, toured around Europe for 4 months and came back to London, sold it in 4 days. Got almost what we paid for it. Only small glitch is that I had to get used to the steering wheel on the right when on the continent. There are lots of places to buy RV's on the continent, Germany, Netherlands etc. They all speak English. Just google them.
7) Our last 7 tours to Europe have been cycling with all of our gear. Stayed in campsites most of the time but the odd time, primitive camped. In Many places this is frowned on. Might be easier in the off season to stealth camp than during to busy times(July/August), when all of Europe and half of the world is visiting.
Good luck no matter what you decide and have a good trip.
