New Camper + Question on towing toys

Assuming the trailer weighs around 700 lbs, you are looking at a 2000 lb tow. It's possible to use the extension, but make it as short as you can. 18 inches would be better. You are going to be weight challenged once you add the tongue weight no matter if you have a Superhitch or not. That would probably be your more pressing issue.
