It's very cheap and easy to stuff "residential" appliances into an RV. That may not make it the best option though.

One thing to consider is the notion that an appliance "made for the home" may not be a good appliance for an RV. Factors like the vibration imparted in an RV,  the shake-rattle-n-roll, size, the way it opens/works, the energy used, repairability, are all really very different between a "residential" appliance and what should be in an RV. You'll find that the top dollar RVs pull heavily from the marine industry for appliances and systems. The marine industry is far more mature and has developed far better systems for tough (i.e. vibrating, shake-rattle-n-roll) and compact, energy restrictive environments. The problem is that stuff ain't cheap.
