To do it proper - yes. Otherwise you're a good chunk over your hitch rating. You can likely get away with it without major issue but if something does go wrong expect that you can get ticketed and your insurance may tell you to pound sand.

More important that the load rating - given this is a u-haul trailer, does it have some type of trailer brake?

 

I did say properly loaded. you could cheat it away from the truck. put MOST of the load on the trailer with SOME additional weight on the truck. Squatin the crap out of the truck is not proper either.

not much annoys me more that done dope pulling the equiptment all the way forward and over loading the hitch.

measure the height of the whatever point you wish load the trailer until there is about 2" of drop from the same point after loading I'll bet you are damn close. make sure both measurements are with the trailer attached.

I think, I said think all tandem axle car trailers that U-haul rents have surge brakes....

a 45000 LB boat? holy buckets that a big one!!!!

 

Yea it has surge brakes, and the only problem here i think is the tounge weight but im going to get a tounge weight scale and make sure the weight isn't too much. And yea the boat is made of mahogany wood, weights a lot with a big ole v8, boat is made by grand craft in michigan.

 

Just watch those surge brakes with winter driving. They work fine as long as the truck has braking traction but if you get in slick crap and the truck starts to slide then they're useless.

What did you use to tow a 45,000 lbs boat with?

 

I suspect the 45,000 is a little off. My dad has a 40' searay with a 14' beam, two 454 chevy's in it and is goes about 16,000lbs.
a semi truck, empty no trailer, about the same.

 

That's what I was thinking. 45,000 would have to be a massive wooden sailing rig with living quarters. I believe that weight would also require a semi and a CDL to haul.

 

hahah sorry for the misunderstanding, 4500 pound boat. not 45000. that would be quite the boat.

 

ahh... gotcha.
