How much hitch drop?

My tow bar, ready brute, said it had to be within 2 inches of level. I have a 10 inch riser on the MH to get the tow bar level.

OP here.

From the rear axle back is the Cat diesel and the transmission. The fresh water tank is maybe a little forward of the middle, so I'm guessing the weight of the fresh water will be a little more on the front axle. Waste tanks are a little closer to the rear, but still between the axles.

I figure that by aiming for a 2" rise with the coach empty, the tow bars should still be good when the coach is fully loaded with water.

FWIW, I've ordered a Roadmaster base plate and ReadyBrute Elite tow bar / brake combo.

The amount of drop on the receiver adapter influences the leverage the toad applies to trying to push the receiver up, or down. It's particularly important in a rapid deceleration. An 8 inch drop will be an 8" lever trying to pry the receiver from the frame, or bend the frame in a sudden deceleration. This was a common enough problem with the early Winnebago Views that had 3500 pound hitches that had that limit due to light gauge frame extensions a third party developed triangular braces to counter that leverage. The hitch on my View had deflected almost 10 degrees before I got those braces installed. No problems after install. I was pulling a 3500 pound Saturn wagon with a 4 inch drop hitch.

I got my 10 inch drop from roadmaster

level is best, but 4 inch up is max

Hi,

I would suggest the 6" drop. A little uphill is OK, but downhill is much worse, as in a panic stop, the nose of the RV will dive, the rear might go up say 4" and if to far, the car can go under the RV! as the hitch bar goes sky high, and the nose of the car is pushed downward.

Also fill the fresh water tank, and see how much the back drops. My fresh water tank is in the basement, under the rear bed, so it will effect the hitch ball mount height. My grey and black water tanks are just forward of that tank, and everything seems to stay about the same as I camp and fill the other tanks with the fresh water. But when everything is empty, it takes 800 pounds off the back of my RV, so I would imagine it goes up 1/2" or so?

Good luck,

Fred.

look on Roadmaster and they will have what you need

Best fow towing is level. You will get all kinds of responses about how much off level you can be. Call your hitch manufacturer to get the straight word from them and not here.
