HP vs altitude & gas vs diesel
Thinking on a new truck... thinking on gas vs diesel...etc. At the moment we need tow capacities in the 13,000 - 15,000lbs trailer weight range with 13ft high frontal area... We live just above ...

It's not gas vs. diesel that is the difference. A turbocharged gasser will maintain higher % of power at higher altitudes too. There just have not been many turbocharged gas engines in thee history of pickups. F-150 Ecoboost does very well at altitude.
Very few people understand this point; it's not a gas vs diesel issue at all.
A "normally aspirated" engine will lose ~3% of its power for every 1,000 foot increase in elevation. Therefore, at ~6,000 feet a normal gas engine will have lost ~18% of its power.
A turbo-charged engine (and all modern diesels in MH's are turbos) will lose ~1% per 1,000 feet. Therefore, at 6,000 ft it will have lost only ~6% of its power.
We lived in Albuquerque for a number of years and our house was at 6,200 feet. All our vehicles were gas but were turbo-charged!
