Best route is probably I35 to I70 into Denver, then I25 north to I80 in Wyoming. Take that to Rawlins, then follow US287 all the way to Teton/Yellowstone.
Not sure how many days you plan for the drive each way, but if you're doing three days each way (roughly 500 miles a day), a great stop would be Loveland, CO, just north of Denver. Johnson's Corner RV park is nice and they have "world famous" cinnamon rolls. They actually are quite tasty. And about 10 miles north is Fort Collins - a great college town with a nice downtown area for walking/eating.
I'd also suggest staying at Fishing Bridge in Yellowstone. It's the only RV park inside Yellowstone, and has hookups. You're going to be driving A LOT around the park, and it's a nice, central location.
That's probably your best route if you want to make the best time, but with one exception. I wouldn't take I-70 all the way in to Denver. You can take C0 79 north from Bennett to the intersection with CO 52, then take 52 west through Ft Lupton, and pick up I-25 west of there, which avoids traffic (and a LOT of traffic, depending on the time of day).
An alternative to Johnson's Corner in Loveland would be Boyd Lake State Park on the NE side of town. While it doesn't have full hookups, it does have electric as well as showers, and is much less crowded that Johnson's Corners, and a LOT less highway noise. Or you could also try St Vrain SP in Longmont, just south of Loveland. Same amenities as Boyd Lake, but a bit closer to I-25 for easy off/easy on.
