Cargo weight capacity

[brainpause]

I am planning on putting a cargo carrier on my sedan, and it needs to be secure, weatherproof, and lockable.

I have found this unit, which I like better than its Thule cousin, because it has a usable tray when removed: Rola Enclosed Cargo Carrier for 1-1/4" (Class II) Trailer Hitches Rola Hitch Cargo Carrier 59108
It is etrailer part number 59108.

Here's my question: The whole assembly weighs 86 pounds, which only leaves 114 pounds to use, because the car and hitch are rated for 200# tongue weight.

I have heavy items that need to go in there, or in the trunk.

What is everyone's experience or thoughts on this? Could I exceed the 200# limit, to say, 300#? Also, is there any driveability change with this setup?

Not an answer but an idea: consider using coilovers which if of good quality should handle the additional weight when needed and be adjusted for normal weight for most driving. Many who use extensive sound system revisions use coilovers to handle the additional weight of amps, speakers, subwoofers etc.

I once drove an overloaded cargo van from Tennessee to Iowa. It felt like the front tires weren't on the ground sometimes. A Harbor Freight Tag-Along Trailer might be a better option if the extra weight capacity is needed.

I second the small trailer idea. Putting 300 pounds on the hitch is not a good idea.
