Considering moving from Diesel to Gas...talk me out of it?

Tomorrow I will be driving up the Moki Dugway. For those not familiar, it is an old ore carrying road that is carved into a 2000 foot cliff face. The grades are pretty much 8 to 10 plus degrees all the way. I sure am glad I have a diesel to haul my 13000 pounds up the road. I would feel the same way going down. Going down with a gasser would mean heavy near constant use of the brakes. With a diesel I would just need to touch the brakes occasionally to keep the diesel brake in the correct gear.
