YES, I do have a compact washing machine that I am having a love affair with! I've had it 7 months and worship it regularly. It takes up less than 18x18 inches square and almost 30 inches high. It fits in the corner of my 28 foot Class C bedroom. It is electric with quick-connect hoses that hook to either my bathroom or kitchen sink.
In my case, where it is parked in the bedroom, the hoses reach around the corner to the bathroom sink, so I hook up the water to the faucet, turn on the faucet, then the drain hose fits snugly right down the sink drain.
While it is only 1 cubic foot inside the stainless steel tub, it is a pulsator, so it does not use an agitator, there fore there is more room for clothes. It does small loads and they come out beautifully! It is a full cycle with wash, rinse and spin. You can program it a dozen different ways and the water level has 3 settings.
The beauty of doing small loads, is that I am able to sort my stuff into different loads, one for towels with extra softener, another for whites with bleach, another for heavy clothes, one for light weight clothes and so on. Usually I do 2-3-4 loads back to back, if I have room to hang everything outside to dry.
For those campgrounds that don't allow outdoor drying, I have an indoor method. In that case I generally only do 1-2 loads, let them dry, then do more until the pile is gone. I don't really pile up much in dirty stuff any more, as it is so easy to wash a small load whenever the mood strikes me.
I put a compression post with flanges in the center overhead of my shower barely an inch from the ceiling. I then have loads of plastic coat hangers which I use for hanging clothes on to dry. I hang those up about an inch apart. I use wooden clothes pins to attach towels and pillow cases etc., to the clothes hangers for drying. If I am in a hurry, I use a clip-on fan to speed dry the clothes. Mostly I let them dry silently overnight, then put them away in the morning. On one side of my bedroom, I decided to add another compression pole with flanges about 8 inches from the wall and 1 inch from the ceiling. That gives me more room to hang things to dry overnight indoors when needed.
Last time I washed my big flat bed sheets, it poured down rain. So I folded them up and hung them on a coat hanger, then aimed the little powerful 12 volt clip-on fan at the sheets and they dried just fine, even folded up and draped over the coat hangers in the shower stall. My big fluffy red sweat shirt dress for cold days, dried overnight without a problem.
This machine has already paid for itself and now I am at the point of saving money by not dedicating 40-60 quarters per week at the campground or town laundries. Also, I took a workamping assignment that did not come with access to laundry. I would have had to drive the camper 10 miles one way just to wash (I have no car.)
I live in my camper fulltime. One of the HUGE benefits of having this washer, is I don't need to own a ton of clothes.
I've been able to wash all my undies, socks, pants, shirts, sweaters, dresses, jackets in it plus all my sheets, towels, wash cloths,dinner napkins, outdoor table cloths and both the dogs beds in it (one at a time). I also have washed my 48" long throw rugs in it (one at a time) on the heavy duty cycle.
Since you can program it to wash only, I stuffed my mucky 25 foot fresh water hose coiled up in it, with hot water and bleach. It washed it without going into the rinse and spin cycle. After it bleached clean soaking awhile, I was able to put it on rinse, which cause the tub to drain, refill and drain again without spinning. My old water hose looked brand new afterwards.
The washer came with two sets of legs, the firm rubber ones or the rolling caster types, so you have a choice. I braided up a fancy rope, then put two hooks in the wall on either side of the machine, so my washing machine is literally roped in, so that it doesn't travel around when I am driving. I can unhook the fancy braided rope, to move the washer (I put the casters on mine) when I want to sweep or clean underneath.
UPS delivered the washer from Amazon right to my camper in the campground, as it only weighs 50 pounds and is made by Haier. They also make one larger (75 pounds and bigger tub) that another RV couple on the forum bought, but I haven't heard back how theirs is working.
My ONLY complaint is that they made it with a clear plastic lid. I find myself fascinated watching the washer wash clothes (amazed at how dirty my clothes seem to be sometimes!). Watching the clothes wash is a huge waste of time, but fun for some silly reason.
One word of caution, read the instructions fully. And never, let me say that again, NEVER NEVER overload it. It's better to do smaller loads than to try to cram a too big load in there. Also, if something is very heavy or bulky (like my favorite purple sweater) then wash it by its lonesome. It will beep you when it is finished spinning. It will also beep you if it gets out of balance, then it waits for you to rearrange the clothes, before it resumes spinning. It does this 3 cycle spinning method, that works really well to seriously wring out the clothes. The first time it spins slow, then it spins on medium, then it spins on super fast.
It takes 20-30 minutes per load, though there is a heavy duty option and a quick option. Also, be very careful about how much detergent you use in it. I was using too much at first and my clothes were drying stiff rather than soft.
I use a Downy Ball softener gizmo in mine, though I buy the cheap softener from Dollar General to put in it. If the water is super hard, I add plain white vinegar to the wash and have a 2nd Downy ball softener I put plain white vinegar in for the rinsing.
Here is the super long link to the Haier washer I bought from Amazon (I could not find it in stock in any stores, though many had it available as order-only). So I just let Amazon deliver mine to me at the campground.

IF I ever trade up to a different Class C or Class A motorhome, it better have room for my washer to move with me as I can't live without it now. I never liked hanging around laundromats and now I don't have to. Hanging up clothes to dry is no bother to me at all. I am just thrilled to have CLEAN clothes and linens all the time. My paper towel usage and cost has dropped dramatically, as I use cloth dinner napkins, cloth cleaning rags, cloth dish rags and so on, saving me heaps of paper towels.
Those newfanlged microfiber cleaning cloths do magic, but don't wash them with the other stuff and never use softener on them. I use them to mop my vinyl tile floors, then toss them in the washer when I am done. Ditto for the outside of the RV and various other cleaning chores.
The only thing that does not fit in my washer is my big fluffy comforter. I've never tried to stuff it in there, afraid it's too big but I have washed blankets, and my favorite queen sized afghan in it.
I so wish the RV manufacturers of the Class C's as well as A's, would get with the program and offer this compact Haier washer as an option. The price and shipping fluctuate at Amazon, no idea why. I happened to get mine for $199 and $50 shipping, then weeks later it was $239 but shipping free. Today as I write this, it is selling for $235 and $29 shipping. Well worth the money and space, especially for fulltimers.
Even a family who just uses their RV for vacationing, could benefit, as then you can pack a lot less clothes per kid etc.
