Hi again,
TV is a 1500 Avalanche 3.73 ratio, rated for 7200lbs, TT is a 19' Passport express about 5600lbs loaded, please bear with me this may become a long post.
around town i tow in 3rd with no problem and I'm happy with the truck response
Now the highway is a different story,
In tow/haul mode the truck holds gears for a longer time and will sit happy at 60mph @ 2000rpm
In D the truck seems to shift easier and does not seem to put as much stress on the transmission as tow/haul, then also sits at 60mph with 2000rpm,
I have been told to only tow in 3rd otherwise the transmission oil does not circulate fast enough to cool
Anyone got any preferences?
The truck is fitted with an AUX trans cooler but i have yet to install a Trans temp gauge, i never tow with the cruise control on because i prefer to use my own judgment rather than the truck reacting too late and shifting down to gears with sky high rpm's when a hill is encountered (better to speed up before the hill and ease off as you get to the peak) not that many hills here in Louisiana anyhow....
any advice or preferences very welcomed from the seasoned campers
Thanks
