Stock 1995 chevy 6.5TD L65 package 4x4 with 3.73 gears, and I will be adding monitoring gauges for EGT, boost, and trans temp.

Could I tow a gooseneck flatbed, with 2-5,000 lb Jeeps, total load of probably 14-15k on the back through the mountains with this?

Will this be pushing the limits of my truck?

What could I expect for MPG with this much weight?

Will my truck die with this much weight? (haha)
