...We'll be coming in from the north and leaving to the south. We pull a 29' travel trailer with our Suburban, what are acceptable roads for pulling a travel trailer within Yellowstone? Do we need to avoid some?...

As stated, the roads in Yellostone are in two loops. Here is a map of the park roads. Speed limit in the park is 45MPH or less. All of the roads are travelled daily by all types and sizes of RV. You will go up and down several times and likely cross the continental divide more than once as you tour the park. In my opinion, the road from Tower to Canyon over Dunraven Pass (8859') has the steepest grades. It is a beautiful drive and one that you will want to take during your visit. If you do it without the RV, you can drive the Chittendon Road to a parking lot most of the way up to the Fire Lookout at the top of Mount Washburn. From the North Entrance to Fishing Bridge it is 4 miles shorter to through Norris than Tower and I don't think the grades are as steep.

Main roads are all good and you won't have any problems. Just don't venture off on little side sight seeing roads without checking first. Some don't have large turn arounds at the end.

There are five entrances to YNP but, with minor exceptions, only one road (the Grand Loop) inside YNP. Since I guess that you'll be coming from Glacier, you'll be entering the north or west gate of YNP and Fishing Bridge is on the SE corner of the Grand Loop. From either entrance its 55 miles to Fishing Bridge. Traffic is SLOW. If you need groceries you'll want to buy outside the park. Expensive, but still cheaper than inside the park.
