Several times a year at a minimum, and not always with good notice.
Towing weight is also a good proxy for frame strength. I do some light forestry work moving and bucking logs, freeing stuck cars, plowing snow in addition to towing trailers and equipment.
I didn't really trust it for some of the logs I was moving, as the trailer hitch was added on after and the frame isn't really designed for shocks like what I was putting it through. On top of that, hauling messy stuff in the back was a pain with having to lay down tarp and hoping it caught everything and didn't rip.
Plus, you can't really put a winch or snow plow on a Sportage.
If it's able to have a trailer hitch fitted, it's designed to have a trailer hitch fitted. You can't just stick it on with a couple of random holes drilled and a bolt through.
I always find it kind of surprising how large a vehicle people in the US think they need to pull trailers, especially when you compare with the size of trailers people pull in the UK. My own elderly Range Rover (1990s P38A) has a plated towing weight of 3500kg which means you can pull another one on a trailer with it easily. With the back full of tools and spares and a couple of passengers, you've got an all-up weight well over six tonnes!
