I am about to move from LA to Temecula (about 150 miles) and will be using a 5'x8' U-Haul trailer. The trailer weighs 900 lbs. empty. I assume the cargo will be anywhere from 1/2 - 1 ton total (high estimate), placed both in the trailer and the bed of my truck. Most of the way is flat land with the occasional up and down grades. I have a 2010 V6 Sport with tow package and Trans & Rear Leaf TSB. This will be my first time towing and I would like to know of any advice you may have for me. I have read the towing bible thread, as well as many others on this forum. I am confident that it should be simple as I am well below tow capacity. My question is:
Gear selection: I want to be in 4th for any uphills but would you recommend OD for flat land? I would like the better MPG but not if it is at the risk of over stressing the transmission. Should I try to leave the truck in D and monitor the Trans Temp and shifting of the truck? If the trans stays in a good temp range and the trans doesnt hunt, is there any risk to wear by driving in D?
I am being cautious here and just looking for advice on anything I may be overlooking.
