Need advice on trailer for 20'

[ledfoot]

Hey all,

I need to buy a trailer for the 1977 20' Sea Craft/150 Yamaha I purchased last month in Sarasota FL.

Is a single axle trailer ok for this application, or do I need a tandem trailer? The single axles I've seen are rated for 3000lbs. Is that enough?

Should I go with disc brakes & stainless hardware, or hot dip galvanized?

What brands/price range should I be looking at? There are two places I know of in Sarasota, Barry's trailers & Trailer Depot. Barry's sells Continental, Trailer Depot sells Magic Tilt (just a name, they don't actually tilt any more).

Are there any brand preferences, large stores in West Central FL I should be looking at?

Thanks in advance!
