Trailer????

Hello everyone,

Thanks for the responses to my last question, my '89 Steplift (200 hp Yamaha outboard) is almost reborn. Now I just need a new trailer for her. I am still using the original dual axle trailer and heard they have come along way since '89.
My friends suggests the following options, but they don't own Steplifts, so your advice is very welcome.

-4,400-4,700 lbs dual axle trailer (by the way, what is the weight of my boat?)
-aluminum
-torsion springs
-disc brakes
-bunker? - I have never used one but they say they are worth the trouble for the ease in maintenance

Any suggestions?? Cost, where to buy, name brand, is there anything I should think about changing?

Thanks
