What does the 350 pounds include? Bike, trailer, load, and rider? Everything but rider? Something else?
People ride tandems with two 200 pound riders and rim brakes in the mountains so your load may be reasonable enough from a braking standpoint with disk brakes.
I don't get the attraction to hauling a bunch of heavy stuff that far on a bike, especially over the mountains, but it undoubtedly is possible. I would just ship the stuff and travel light, but it is your trip so do what makes you happy.
