My initial reaction is that you should be fine. If you're properly set up, a vehicle with a 3500 towing capacity should be able to handle an RPOD pretty easily. That's the same capacity as a compact pickup like the Tacoma. Just for comparison sake, I towed a teardrop, (1100 lbs dry, probably closer to 1500 loaded), to Missoula last summer with a 2000lbs towing capacity CX-5 and other than a little sluggishness in the mountains between Helena and Missoula, I had no issues.

Of course, that assumes you have the proper equipment. Do you have the towing package that mark mentioned? Do you have a 7 pin wiring connection and a brake controller? Those are as important of factors as the vehicle itself.

Are you from Missoula or are you going there to pick up the camper? The areas you're most likely to have difficulty are right around Missoula, so if you're from there, give yourself a test run in the area and get a feel for how it handles before getting out on a long trip.
