I see what you did there!My issues were all with power. Felt plenty stable. Brakes worked great. Just struggled on the uphill, which was the whole journey. I bet their not bad tow vehicles east of the rockies. But Im changing 5-6k elevation in the first 100 miles from my house so it was kind of a drag.
People tend to freak out over rpms, but these overhead cam motors have no problem with extended work at 4,000 rpm. I am happy to downshift as necessary for hill climbs.
