I highly recommend a nice MotorHome,
just don't buy some underpowered (usually gas, 5 mpg)
POS C-class/van conversion
97 Safari diesel pusher,
Magnum chassis 360hp Cummins turbo diesel/Allison 5 speed
you can get them used for "relatively" cheap now
I had one when it was New to 4-ish years old, $100k+, sold for $80k
nothing like a nice class A Motorhome, traveling in comfort & style
like driving your couch down the hi-ways
(slept 6 pretty comfortably, shower/bathroom/kitchen, couches,
queen size bed in back over engine cover)
problem was needed to flat tow,
an alum Featherlite 28ft trailer over 11,000 #s loaded 2 cars
my altered & a top sportsman car
& a bunch of places we used to stay at, along the way
won't allow that long of a trailer & rig overall length, past like 45 feet combined,
made for a hard time on the road
& staying at camping spots along the way, I used to always stay at
almost 30 years old now they can be had a lot cheaper
but insurance is still high
Mine got 14-16 mph, most anywhere, towing at 75
if I didn't keep my foot in it
went back & forth across, a lot the US like 15 times, from Calif.
It's like there's not even having a trailer behind it, going down the road
parking it & fueling up, with a really long wheelbase rig is another issue...
you learn & get used to it
I'd say buy the nicest one biggest diesel powered one you can afford
you go cheap & it will bite you directly in the ***, leave you stranded
& having that **** towed is very expensive
so are/is diesel maintenance too
good luck
