I have two questions: (1) I'd like opinions on the best trailer manufacturer for what I'm planning and (2) I'm trying not to exceed my tow rating. I definitely want a roller trailer and expect it to be dual axle.<br /><br />Here's the details: I'm hoping to buy a 21' 2000 Sea Ray 215 EC that weighs 3800 lbs. It doesn't come with a trailer and I will be trailering it in salt water and rinsing with fresh water after each use. I'll be towing about 2 miles each way, pretty flat. My truck can tow 5800 lbs so I'm looking for lighter trailers. I'm thinking the best idea is to get a new one. My existing 19' boat has a loadrite trailer that I'm happy with.<br /><br />Opinions on manufacturers? Are aluminum trailers lighter? torsion suspension?
