Best/Fastest route to Edmonton from Florida

Hi! We are driving to Alaska from Florida once again. We did this trip in 2013 and it was great. Last trip we had about 7 1/2 weeks total, this time we are doing it in one month! We camp out of our SUV with occasional motel in US. We boondock as well. We do not fly and love to drive. Our main destination is fishing on the Kenai. We are fishermen/woman! We normally drive the first 24 ours non stop, while one sleeps in the back. This is a normal thing for us on our vacations and we do this yearly. My question is, this time we are not sightseeing through the Black Hills area and Ice Fields as we did last time. We do not have the time, so I am looking for the best route to get to the ALCAN and then we slow down.....Last trip even with a lot of sightseeing we made it to the AK border in 7 days. Crazy I know, but we love to drive till dusk and look for animals, I always stop for photos etc... Then when we get tired we find a place to pull over and camp. I know we miss a lot of historical sight and such, but we have a business that we must be back to and fortunate to get away again this time. Hopefully as we get older and are able to retire we will take longer, slower trips but right now it is for the fishing!! AAA is giving me two different routes, one takes I29 out of Fargo up to Winnipeg and then CA 16 over to Edmonton, the other takes Fargo to Minot up to Regina Rte 52. I've heard ND can be crowded these days with the fracking. Last time we took I 90 through SD to Montana and crossed East of Glacier NP, may have been Sweetgrass. Would appreciate your input on a route, even thought we won't be lolly gagging scenery does help the trip, so I will keep that in mind. Thanks!
