Bundymark, keep in mind everyone will be like 'I'm SOO Happy!' with the hitch they have just purchased (or been sold
), even if they have never. ever. used any other kind of hitch
Also consider that mud, dirt and stone strike/gravel rash can wreak havoc with delicate sliding plates, machined pins and the plastic shrouds that some hitches feature.
Compatibility with a standard tow-ball is an asset (a must for me personally) as it allows carriage by other vehicles in a recovery or emergency
Balls are also often easier to line-up (compared to pin types) when hitching, although that is not much of an issue if you simply leave the car attached when camping. And you can't lose the pin.
TBH, a stock standard trailer hitch can go a LONG way off-road so maybe start with that and 'upgrade' later if actual situations deem it necessary.
Hope this helps
