you confuse me on frying pan. if you take hagerman it'll dump you out at basalt. you don't go back up independence. from basalt go over pearl or go south to carbondale and then to marble and schofield or keep going over mclure pass to kebler pass. depending on what you feel comfortable with. I doubt Pearl will be open by then. if it was a lean snow year it would be but It's not usually passable til aug for your type of rig. esp going aspen to CB.
See you on the trail
