Hitch / receiver extension question

Depends on what you plan to pull. Small boat or utility trailer is totally different than something bigger or heavier. But you can easily get a reducer from 2.5 inch to 2 inch. That is only going to work for a small light trailer though. You might just want to upgrade to a torklift superhitch, which I think will mean you don't need separate rear tie downs, just front. The time to decide that is now, otherwise you will have wasted the $ on the rear tie downs. With the superhitch you will still be able to use that extension within limits, but if you are towing much you'll have to go with the torklift double extension.
