Where did you get your trailer made and if you don't mind saying how much was it?
I just realized I forgot to answer your question regarding the trailer. I looked around at used dual jet ski trailers. Found a few that looked workable, but by the time I found them, they were sold or too far away to go after. The Malone and Trailex trailers made for kayaks run anywhere from $1300 to $2000 from what I have seen. They sit higher off the ground than I wanted. My neighbor has a custom made aluminum trailer that a gentleman down in Gainsville, Florida makes. The neighbor's setup is a stacked setup (one over the other...single wide) style. The gentleman that makes the custom trailers also makes side-by-sides. He quoted price was a little too high for me.
Since I wasn't finding a good used trailer that I liked, I convinced the "commander-in chief" to buy a new one.
The one I have is made by Aluma. 5-year warranty. Weighs a little over 200 lbs. Easy to move by hand. It's a PWC 2 model. Most are selling at trailer dealers for an average of $1600. I got mine for $1379. Hard to turn that price down. While I do have a bed extender, I rarely use it anymore. The 2 PAs stay on the trailer for storage in the garage and I keep the 2012 secured with a good security cable and lock. That way when I go by myself I just rig up the 2013 and go. The height is perfect for just sliding it off the back into the water at the ramp. I have yet to put the trailer in the water and float off the PAs like a regular boat.
