Just recognized Teton Pass has 10% grades. Pulling a 23' TT. I have never seen a 10% grade. Leaving on Tuesday. Comments, suggestions.? Safety is always my number 1 concern. Thanks.

With what?
If you have adequate power and food brakes and know how to downshift in order not to overheat your brakes and don’t ever ride them you should be fine.
And that includes making sure your trailer brakes are in good shape and of course you have a brake controller
Even here in the East we have 12 and 14 percent grades

No personal experience with that road. We only see 10% once a year heading into a favorite campground and it's only 1/4 mile long but with a hairpin turn at the same time.
And we are only moving at about 10 mph in both directions.

This discussion may be of some help;

Gear up = Gear down - Short firm brake if you have to gear down.
My preference has always been manually control the gears. Old school.
When going down hill and the speed increases to fast you have to gear down to the next gear. The engine has to hold your combination. Using to much breaking will increase heat on drums and pads.

Do not rush yourself even if others pass you.

a total aside. Our first steep grade we were presented with after getting our first TT was a 14 percent over two miles on gravel going to the campground.. I was a little worried about getting out as the gravel was real loose.

Did not stick.. Did not even spit gravel everywhere. So when we encountered 12 percent coming out of Oak Creek in the Sedona AZ area it was a piece of cake.

Pass

I live in Jackson and drive the pass often. Id make sure my brakes were in good shape but other than that youll be fine. Lots of trailers all summer. You can take an alternate route. Where are you coming from?

When going to and from Grand Teton I skip the pass and go through Alpine WY to Idaho Falls WY. You could do the pass but there are alternatives, so why do it?
