Only a Utility trailer or eventually a Horse Trailer?
For New vehicles, my rule of thumb is look at towing capacities of vehicle's claimed towing capacity and subtract 25% of what the vehicle is capable of for non-animal trailers, subtract 50% for animal Trailers as a maximum combined weight of trailer and what you are hauling.
Reason is I think manufactures are pushing the max limits on their vehicles to look better than their competitors and also life if vehicle increases when you do not push the max limits.
A towing Package is needed and Trailer Brakes on the Trailer, unless you stick with a small utility trailer under 2000 lbs.
Brands? Anything but a Chevy ....lol.....
