I am planning a road trip with my fiancee starting in Minneapolis, MN to Arches and Yellowstone National Parks. We have 6 full days for the entire trip (it is over our spring breaks). We do not want to stay at hotels, but rather we would like to camp along the way in a tent. We want to do a lot of hiking...

Yes it's possible. I've done entire road trips where I only camped, or sometimes crashed in the car for a power nap when driving in between places.
You will have a decent drive between each of these. Personally, I would plan out the drives so that we drove straight through and took turns driving and that way were able to spend as many "daylight" hours in the parks. However, that isn't for everyone. There are plenty of websites that can hook you up with campgrounds along your chosen route. Be sure to take into consideration the "time" when choosing your stopping spot. It's easier to raise a tent in daylight, so you'll want to watch the time. Have a list of alternative campsites available in case bad traffic creates a delay.
There is plenty of camping in and around these National Parks.
Feel free to drop me an email with specific questions, I've been doing road trips for a long time and when I was younger I cut a lot of corners to save money. I learned a lot of tricks along the way.
