Just got back into a 6.4 and am getting ready to do a build. I would like to do a single 68 or 72 but what is the reality of the situation? I live at almost 5000ft elevation and tow over the mountain (10,000+) a few times a year. Is it still possible to run a single in this situation? Shooting for 700ish Hp.
