Too close to tongue rating?

[Azhjph]

Have 2010 4WD Lincoln navigator rated at 900# hitch.
Now pulling a TT with 550# hitch weight with no bouncing. If new TT is 750# hitch, will I get rhythmic bounce and if yes, what to do? Thanks.

A weight distribution hitch will help. But also make sure the fully loaded weight of the TT and the cargo including people in the Navigator do not exceed the max tow rating of the Navigator. Your Navigator may be able to tow the TT down the road but can it stop, will the brakes, tranny and cooling system handle the load?

Hi, Azhiph, and

A 2010 Navigator receiver has a hitch capacity of 600 pounds with a weight-carrying (WC) hitch, and 900 pounds with a weight-distributing (WD) hitch.

If your Navigator has the heavy duty towing pkg, then with a WD hitch and with nothing in the SUV but a skinny driver, without being overloaded you can tow a trailer that grosses up to 9,000 pounds or that has hitch weight of up to 900 pounds, whichever comes first. However, if you have the regular towing pkg, then the max trailer weight is 6,000 pounds and the max tongue weight is 600 pounds without being overloaded

Now pulling a TT with 550# hitch weight with no bouncing. If new TT is 750# hitch, will I get rhythmic bounce and if yes, what to do?

If your Navigator does not have the HD Towing pkg, then you cannot tow a trailer with more than 600 pounds hitch weight. If your Navigator does have the HD towing pkg, then you must have a weight-distributing hitch properly installed and adjusted for the actual wet and loaded tongue weight of your trailer. With a properly-installed and adjusted WD hitch, you should have no problem with rhythmic bouncing.

There's one caveat: a few roads, especially concrete ones that have begun heaving from their separated slabs, can sometimes be so bad that nothing short of a hovercraft will eliminate bouncing.

How bad it will bounce is a rig-to-rig wildcard.

Some rig combinations, even though otherwise very steady, will make you hit the ceiling if it weren't for seat belts.

But that doesn't stop us from getting out there to give it a go.
