First long trip with the trailer : 2 full weeks and about 4000+ miles, didn't get any issues at all.
My trip was
http://mapq.st/QpRv9S- Seattle to Bozeman MT
- Bozeman, MT to Yellowstone NP and Gd Teton NP
- From there to Logan, UT
- Logan, UT to Capitol Reef NP, UT.
- Capitol Reef NP to Moab, UT (Cannyonland NP and Arches NP)
- From there to 4 corners National Monument (UT/CO/NM/AZ)
- Then Monument Valley, AZ
- From there to page, AZ (Antelope canyon)
- Then to Bryce Canyon NP, UT
- Then Great Basin NP in Nevada (very very lonely road : UT-21)
- Then back to Seattle, saw Shoshone falls in twin falls, Idaho on the way.
Plenty of high elevation on the way, many 8k+ passes over the great divide in MT/WY and also in UT
Highest I went is 10.000 feet at the Great Basin Lehman peak campground (highest road and campground in NV)
Didn't really have any issues pulling the trailer, but I usually would try to keep it under 3k RPM, 4K max on steep uphills ... sometimes than meant going 45 on the few very steep grades over 7 %
What felt the steepest was probably the long steep grade out of garden city, UT up beaver mountain (highway 89) ... not sure what the grade is but it's steep, long and steady.
Other slight annoyances are when there are hgh speed(75/80 mph) limits on highly freeways like I70 in Utah, hard to keep up with the trucks there !
