I just did a simular trip
I pulled my TD to Tahoe and back from San Francisco
with my Meyers Manx dune buggy. it was about a 650 round mile trip.
I did it with out brakes as well and I have a bigger TD.
So taking your time is the key and staying in gear on the downhill.
I was conscious of the braking the entire time but it was enjoyable.
To do it again I will have a surge brake though so I can take that thought element out of it and make the trip even more enjoyable But it's worth doing and the only way to learn
My bigger issue was the wind , which was not fun at all crossing the Bay bridges. I was in full pucker a few times from the cross wind and had my speed down to under 25 mph. I had plenty of power on the up hill with my 2330 but as long as your over 1800 cc ou should be fine, Under that could make for a real long journey.
