For my 282 Sailfish, I have a Road King RKAV 26-28 TRB3 w/15" D rated tires. Electric over hydraulic brakes on all 6 wheels.
Don't skimp on your trailer!
That's a nice trailer. Are they putting Tie-Down or Kodiak brakes on them now?
For the OP, here's an example of a heavy duty trailer for a bigger boat.
Roadking specs on this one:
RKAV 26-28TRB 80" / 6.5 225X15D Radial
15200 LB GVW
13000 LB LOAD CARRYING
You might get by with a tandem with the 16" LRD tires, depending on your actual boat weight:
RKAV 26-28TB 80" / 6.5 235X16D Radial
12000 LB GVW
10000 LB CARRYING
A tandem is a little easier to make turns with when manuevering.
Personally I would prefer the heavier frame rails, 7.5 or 8.5", but from their specs it seems the axles and tires are the limiting factors for the GVW rating.
I have 4.5" frames on 6K lb GVW for my smaller boat, and I think they are too small. I have had some issues with flex, and it's critical to get all the supports setup correctly or there can be problems. Mine was definitely not setup right from the factory/dealer, whomever that was. Quite a lot of tweaking to get it right, modified bunks, I could go on... :roll:
