Hey guys, We are trading in our 2009 Surveyor on a 2022 Open Range 26BH. It is 29 feet, Gross weight 6500, with a dry weight of 4700 Lbs. My truck (2013 f150 5.0) has a tow limit of 7700. The weight ...
The 10 speed didn't come out until after 2018 I think? I've got the ol' 6 speed same as you. I do lock out 6th, even on the flats, as the Eco likes it between 2000 and 2500 rpms for the most part. In my case, it helps keep the engine from 'lugging' too much and actually using MORE boost at the lower rpms.
I monitor all temps and other vitals with a phone app and a ODB2 adapter and that really helps my towing too.
