Just spent a few weeks to a month on this, my local dealer beat the above mentioned with a-
New Tandem Axle Bunk Pontoon Trailer with:
*Triple Tube Kit (Bunk Supports under all 3 Pontoons)
*Tandem Axle Disc Brakes (10" Discs)
*Stern Extension Frame (Frame & Bunk Support Extended under Center Pontoon)
*Plastic Bunk Wrap
*Galvanized
Standard features:
>Deluxe Winch Stand with Large Step Ladder and Handrail
>Heavy Duty Winch (3200lb)
>LED Lights
>13" Radial Tires
>Galvanized Rims
>Steel Fenders
>Dual Wheel Tongue Jack
>4" Box Tube Steel
>3/16" Steel Side Frames and Cross Members
>5000lb Capacity
etc for a 22SSBXP tri toon trailer by about 400.00 but I found that for my boat, most trailers were coming in around that 4K-4500k.
Th only thing I was really missing was a torsion axle, but the more I talked to people, the more I got steered away from it..plus we plan on traveling with our toon so I want more than just a storage jockey.
Good luck in your search.
