1st go here
and download the pdf file to your desk top.
(Right click on the link, choose "save as" and save it to your desk top.)
Print a copy of it.
I believe your steps 1 - 3 are correct.
That file tells you how to adjust the reese hitch but doesn't say much
about the head angle.
Mine is set with the offset.
The WD bars are sized according to your anticipated tongue weight.
Tongue weight should be at least 10% of total trailer weight.
You don't say what your new trailer is supposed to weigh.
If your tongue weight is say 500 LBS and you put on a set of 1200 LB
bars you are going to get very little flex in the bars and a rigid stiff ride.
Mine are 800 LB bars and they are a little too much for my trailer but
my dealer said they were the lightest he had or the lightest they make.
I'm not sure.
After you get hitched with the bars in place and a decent amount of
tension on the chains you need to go someplace where you can drive
straight ahead for 50-100 feet. As straight as you possibly can.
Then get out and look at the position of the inverted V of the WD
bar as it lays on the cams. You can get down and peak thru the hole
where the chain hooks onto the outside of the cams.
The bar V should be centered on the top of the cams.
This is shown on the bottom of the last page in the PDF file I mention above.
You'll need a big adjustable wrench or box end wrench to fit the cam arm
adjustment nuts. The file does not say what wrench size that is.
I'm at work and can't measure mine for you.
Since you are changing Tows and not trailers, you may be OK and not
need adjustment but you want to get down on your squatter and look!
When I'm hitched level I have 3 loose chain links hanging. I'm hooked
on the 4th link of both chains.
This is how I would do it.
I'm not an expert.
Use your best judgement.
