my 5.3 tries,
basically i run it at 65 mph, in 3rd gear so it dont shit can the overdrive. 3000 rpm usually
hits please 5200 rpm or against the rev limiter, sounds like its going to throw a rod some times.
but the trip to waynoka for me isnt to hilly just bucking the wind can be a bitch.
last time i went there i got 7-8mpg. at 65.
yeah a diesel is the only way to go, im looking a dmax or stroke, just got to work some funds around.
bansheefreak pulled my trailer last time, it honestly downshifted into 3rd gear like 4 times if that. usually could unlock the torque convertor and just pull. i was like must be nice. he has a dmax.
