I'm assuming your 35' bumper pull is the entire trailer. I have a 35' bumper pull toyhauler (Stealth WA2916) and on Forest Service roads I'm more watching for the overhead trees than anything else. But yes we've had to adjust some of our camping sites to make sure we grab the longest ones.
This setup is only 5 feet longer than our Truck camper plus enclosed trailer but the toyhauler cuts the corners much more when cornering.
Note that we are (so far) keeping our TC for when we want to fit in the small spaces and not take our toys. Like Glacier NP in a couple weeks.
