Yes, it seriously took that long. Thing is, in ND, it's all Air force bases. So, the movers from AF base came down to pack up our stuff, and then they were supposed to send it on to Ft Polk. They never did, DH had to call a couple of times before they even got it on the truck to us.
You'll be driving thru mountains, those are horrendous in a moving truck(hell, they are in a car too, I was white knuckled our whole trip thru the Ozarks)and I was in the car! I don't know how DH did it in the truck.
The gas tanks on moving trucks are huge, and 2 years ago, it took over $100 to fill it. Plus the gas on my car. And every 700-800 miles, we had to fill up both vehicles. That alone would cost a decent amount of money.
Then you gotta figure hotel costs(and most don't take dogs) food, etc. We ended up making very little, and it was so NOT worth it. We swore if DH re-enlisted, we would never do another DITY move.
