RV, Class A or Class C Motor Home

Motor home, 28 feet or bigger. Prefer Class A, but Class C will be fine also. Must have room to sleep 5 people, something with bunk beds would be great. Must be in good running condition, no leaks, EVERYTHING MUST WORK!! Please understand that I will be LIVING in this motor home with my 4 children for an indefinite time, so it is essential that all air conditioners, heat, fridge, stove, generator, water pumps, toilets, etc. work without problems! I can clean/replace carpets, wash down interior, and other small things, but I am not a handyman so I need something in decent condition. Thanks!
