Trip update: made it to eastern Washington yesterday, Snoqualmie pass proved to be a force to be reckoned with. The load combined with the boat on top made overdrive an impossibility and as long as the rpms were above 2400 she cruised fine, 3500 was the upper limit I didn't feel comfortable going over so I had to be diligent the entire time.
I really think the transmissions in these aren't suited well as the tach drops below the power band in 2nd before 1st is even approachable! Yes, at the top of the pass I did actually drop to about 35mph, mostly carried 50 though!
70-75 came up a few times and it was surprisingly stable!
Unloaded this trailer specs out at 5600lbs so I'm guessing with all our stuff we were at about 63-6500 plus the boat and motor, us, and then the dogs and their kennels. Yah, with 3.55 gears and larger tires I'm glad she did as well as she did!
Averaged 8mpg with AC on most of the way (turned it off on the pass).
