Just bought a 26' boat - will my H2 have any prob towing with stock setup

[dna]

I estimate the boat at 5,000 lbs; the roads will be generally flat; yes I have the air suspension. I assume I should use the "tow" button/feature.

Yes the trailer has its own brakes. I have never had a boat or any heavy trailer with its own brakes. What is involved to hook it up? What if I drove 2500 miles without hooking up the trailer brakes and only used the H2 brakes?

Thanks
