this is more or less a copy of what ive put on a diffrent site, figure i mite get more ideas hear as well

i set Google to its terrain mode, to help show the differences in passes.
my question is, having a avrege of 4,000 versus 6,000 feet thru the mountens, is that enuf to drive about an extra 100 miles to be a lower altitude

northern route its the one that's 100 miles farther, one pass at 6,000+ one at 5,000+ and one around 4,000 something.
I-84 to US 395 then I-90 across and down to I-25 for a short ways, then US26 too I-80
the other plus of going this way is for more then one grade your along a water way so the grade-eant is rather mild....
I-205 S to I-40 E - Google Maps

southern route I-84 all the way to I-80 east word.
two passes around 4,500 two at 5,500 one at 7,500 and another at 8,500
also for just about all of WY states 400 miles your at 6,000 to 8,000 feet

I-205 S to I-40 E - Google Maps

bolth ways still keep me in WY and MO state with lower priced fuel so that's not a issue.

my ride is a turbo model, but there are others making the trip that have the N\A model in the 2wd models.
a little info on where im headed.
