I'm going to pay more attention to some of the 12,000-14,000 lb. trailers I see being towed and parked. Try an look at the hitch and educate (or learn).
What is the trailer weight rating (without equalizer) on factory hitch 3/4 ton trucks? Haven't looked at them for a long time and can't remember if the factory hitch would be OK for 14,000# bumper pull without equalizer. The thought of 14,000# on a 6000# ball (Reese stainless) is still scary.
My main trailers I own/tow are an old 12 foot dual axle skid loader trailer and a single axle equipment trailer with my 1/2 ton. I do have a 27 foot boat (4 cylinder gas) that was set up for an equalizer hitch that I only use the regular ball mount to tow it 30 miles twice/year. Haven't towed it for a few years. The 23 foot boat I do use puts me right at legal limits and I've been a little over combined gross on very long trips. That trailer needs a equalizer hitch mounted on it which I've bought and haven't put on (Pole tongue adapter).
I now have a 2001 Ford 1 ton single rear wheel truck I set up for an Alaskan truck camper that has steel utility box and front winch. Old railroad electricians truck. I have it loaded at max rating and would like to have 19.5 tires but rims are not available for it (that I found). Haven't needed to use it for towing yet. Just plan on using it for smaller boats but need to make sure it's ready if I tow the big boat.
I am a truck driver and more careful (safety type person) than most.
