Very nice! I've found it difficult to get my Aisin transmission temps over about 170 - kinda amazing. The Aisin is a workhorse. It usually runs about 168 degrees, regardless of what I'm doing - empty or towing. And 98 degrees outside temp is pretty hot!
I don't worry about going over the 14K since that is a class 3 limit and really means nothing. I am under the front and rear axle ratings.
I towed over highway 2 to Eastern WA from North of Seattle. Slowest was 44mph in 3rd all temps were very good! That was some steep grades coming up to the summit and then some after crossing the pass for sure over 6%. On the way back we went over I-90. The grade coming West up a long grade from the Columbia River is called Vantage Pass. With my 11 HO Dually towing a combined 30K I pulled it at 58mph. The new truck and RV grossing at 32,540# pulled it at 62 with no issues at all in 4th gear. Then pulled Snoqualmie pass on I-90 with cruise set at 60 with no problems.
Can't wait to pull I-5 South to compare my speeds with my last RV and TV at 30K.
Very impressed with the whole experience. Rear air ride is for sure an improvement over my 11 even with Bilstein's and air bags.
This is Stevens pass HWY 2
