I can only relate personal experience.
We lived full-time in a fifth wheel in which there was a Splendide combination vented washer/dryer. That thing did 2 loads of clothes nearly every day for over two years, with no trouble at all!
Each load consisted of one set of clothes; that is, underwear, socks, shirt, trousers. Keeping the load light like that pretty much eliminated wrinkles, even though the loads did not always get removed from the drum in a timely manner.
We were well pleased with the vented Splendide combo unit.
