I was wondering if it is worth buying 2 parks passes one for MH the other for the towed or just one, I know they are $80 apiece any help is welcome

Only need two if you plan on driving both vehicles into the park at the same time.

Even then, I would suggest attaching the toad, driving in as one, then separating inside the park.

Another thing to consider is you can upgrade your entrance fee (like Yellowstone) to an annual National Parks pass within 7 days, by paying the difference. Just save your entrance receipt and drop by an entrance booth, or even a visitor center.
