Update. We made it home fine without the WDH. It swayed just a little bit not enough to give me the white knuckle ride home.
We had a 15 or 20 mph headwind with just enough cross wind to mess with towing any rig. I ran about 60 to 65 mph with no issues. I averaged 11.7 mpg on the trip home. About 30 miles on I-4 and maybe 7 miles on urban road at 50 mph.
We towed with our 2017 Colorado crew cab short-bed pickup. No real effort pulling at all, but it's the Duramax Diesel with 6 peed auto.
With out bars it dropped the rear truck height down by about 1 and 3/4" and raised the front by about 1 and 1/2" up.
I will address that with the bars when I install them and set them up tomorrow. Shooting for as close to unhooked height as I can get on the front and rear axle when hooked up.
I have to get truck and trailer on level ground and determine what the ball height is for the trailer and then set up the hitch to the same height with with truck level and not hooked up.
Then play with the ball angle and bars to get it level when hooked up.
I'll update more after that is done. Goodnight and God Bless .
