I just bought (last week) a 2010 Salem 23fbl and an equalizer hitch and as it turns out was looking at a Surveyor sv 264 but it was sold out from underneath me by a private party.
NJLOAD, your hitch weight is about 500lbs depending on the exact year. I just bought a 600lb Equalizer hitch (model 90-00-0600) for $560 dollars from the dealer, installed, setup, and hooked up to my trailer. They wanted $800 for it and I told them they were going to have to do better than that hence the $560.00. I already took a 3 day trip in my TT and am pulling it with a 2001 Tahoe 5.3L 4x4 tow package and that hitch handled that whole setup like a boss. Money WELL spent. My advice to you would be to spare no expense for safety and piece of mind. There is nothing worse than white knuckling it while you are on "vacation."
A big reason I got this hitch is because any monkey (read me) can hook it up and adjust it and this hitch is designed so that you can back up with it even at tight angles. (Been there, done that already.)
This hitch is made in the USA and goes for $553 on Amazon if you want to install it yourself which is actually very easy.
This is my first TT, first sway control hitch, (not first time towing a trailer) and was my first trip and that hitch made my trip worry free and unbelievably easy. Made me wanna go camping everyday.
Do it. You will not regret it. But if you do you can blame it on me.
Congrats on the trailer that is a sweet one. The trailer I got is the same idea as the 264 but no slide and steel frame.
