We will be in Utah middle of April seeing the sights and then on to Arizona. We are towing 27ft tt how would we do on 89a from Kaman to Bitter Springs, then 89 down to Flagstaff. Thanks.
You'll do fine. I've driven it in my motorhome with tow car. You will ascend through the cool pines to Jacob Lake, then descend the other side with large sweeping curves and stark panoramic views. Will you be visiting North Rim Grand Canyon?
And 89 down to Flagstaff is very easy, through Indian reservation land. Can be windy (blowing air, not curves) though.
