Can I use regular household appliances rather than RV appliances?

I am going to be converting an old school bus into an RV-type vehicle for my family and I to travel in. I am trying to keep costs down as much as possible, and have found that RV appliances are a little pricey. Can anyone (especially someone with RV experience, please) tell me whether or not I can buy standard household appliances (stove, refrigerator, etc.) in place of RV appliances. If I do are there any drawbacks, etc? Also, I will most likely be using a combination of solar and wind power as my main energy source--would there be any additional info I would need to know?
