I agree with the idea of overbuilding a trailer. It's like HP, you can't go wrong with more. But one word of caution would be that you don't want to go too far overboard with the capacity. If you get a trailer TOO much "overbuilt", you run the risk of creating a very harsh ride for the boat. If you've ever ridden in an older, 1-ton duallie when unloaded... you know EXACTLY what I'm talking about! :mrgreen:
I also think there's much to be said for buying a quality trailer and not just buying based on cost. I think that the better trailers start with better quality components to start with. While ShoreLand'r is not the only "good" trailer manufacturer out there, I'll use them in an example. Aside from owning a few of them (and I do a lot of trailering), I also work part time at a Sea Ray dealership (for about 20 years, now... crap, I'm getting old!). Sea Ray has packaged Shoreland'r trailers with their boats since 2001. They are "spec'd" with roughly 5% (give or take a bit) extra weight capacity, over and above boat/gas/batteries. It is EXTREMELY rare for us to see a customer come in with a bearing issue. And we have a decent amount of customers that, when we remind them about "good maintenance procedures", will say to us "Grease? I have put grease in where?" :roll:
My point is, I think that with your better trailers, there's a sort of "margin of error" already built in, even though the official specs may not show that. And also that the components they use are of better quality to begin with.
I also agree that there are plenty of places - ESPECIALLY online trailer purchase places - that are selling based on, primarily, cost. And therefore may overlook quality and reliability for a quick buck.
