I'd caution you on selling your Scamp - at least right away. If you want to take a bunch of little trips or go to rustic or remote places, then you've got the rig to do that. Big trailer is hard to do that with, but definitely more comfortable if you are gonna park for the season.
Actually had considered keeping it for that exact reason!!

Hey Carol something else you need to be sure your truck has is an electric brake unit. In Fla. you must have that to connect to the electric brake on the trailer if the trailer is over 2000LBS I believe. Either way it is best to have it since you dont want to be stopping a 4000+ lb truck and a 4000+ trailer with just the truck brake. Think jack knifing and hot brakes. IF the truck doesnt have one with the towing package it can be added at the RV dealer or U Haul.
So to recap: You need a electric brake unit, a weight distribtution and sway control hitch. These are must have things for safe towing.
