Best route from San Diego to Indiana heavy load

Ok I'll upload u a map

 

U want to avoid hills that southern routes just for u!

 

It wouldn't be that unusual! Even at 30k it's a bit slow and gutless ....bet heck I'm down to 25 mph on some grades.....depends the grade...never heard of devils canyon ....what road was it on and the grade in New Mexico

 

Well .....that hill from Phoenix to flagstaff or the hills Phoenix to Holbrook (2 different routes) go from near sea level to over 8000 ft! I'd go that southern route to avoid the hills...but it's the burning hot desert lol pick your poison

 

Yeah lol that's gonna be your worst hill like I said the l8 has a few of the worst hills .....I'm not sure there's a lot wrong with the pulling power it's the hill!

 

I'd go back the way you came

 

5-10 mins at 30 or 25mph on those hills won't kill ya man .....u can't go 65 always

ummmm it's a long slow climb out of san Diego back to the desert
