We have had a stacked Whirpool set since the trailer was new--recently replaced them both because wife wanted a front-load washer. Yes, you will need to vent the dryer--a daunting undertaking 'cause you just worry about opening a big hole in the wall in maybe the wrong place...there are ventless dryers, but you won't like them.
Whirlpool has an apartment-size set, Splendide if you want to get spendy, there are others. Just be sure you are looking at 110volt dryers, not 220.
And my wife is surely with you on your point of view on the laundromats...
