I have seen a washer dryer set up in the bedroom of a couple of new units I saw at a RV show. Don't know how common it is though. Many RV's don't have a sewer hookup from the washer to the grey tank, only to the outlet past the grey tank, so you can not wash while dry camping, only with full hookups. Probably a good thing anyway, because they would quickly fill a typical 50 - 60 gallon grey tank in only 2 wash loads.
Personally, I don't like the washer, and have used campground washing machines, or more commonly would spend one day every 10 - 18 days at a laundrymat. I put everything into the washers at once, even my undies are blue, and no need to sort colors. I picked out the extra large machines that tumble the clothes, they sometimes accept 12 - 18 pounds of clothes per $4 or $6 washload. And then split it into 2 dryers per washing machine, to dry quickly. Be done with all the laundry in only about 2hours, including folding time.
Check the size of the laundry machines put into most RV's. They typically will hold two pairs of blue jeans, and take forever to dry on the 1,500 watt setting - 1/3 the wattage of most electric dryers. This is because they are 120 volts, not the 30 amp 240 volt 4,500 watt versions found in homes.
You might also consider a "toyhauler" that can haul around a car sometimes, and your other stuff. You can put full sized recliners into the back when the car is out. Keep the car very light, like Honda Civic, under the 2,000 pound ramp rating.
Good luck!
