Also went across Big Horn with no trouble. Stopped at top and detatched toad for DW to lead with. I had a brake overheating problem once before, and didn't want to worry about it again. V10 with HHR toad, have done Smokies, Osarks, ( into Branson), and Yellowstone with no problems. We started the thing of detaching the toad going way up into the mts in West Virgina on steep, twisty, narrow roads. DW in front with radio to check road ahead for traffic and other nasties. Another is the campground at Norris Dam above Knoxville, TN. Can check taillights on toad on some of the hairpins. So, no problem with 30' gasser going anywhere.
