That trailer is pretty light - My little 5x8 flat bed is 700 lbs empty. You will question yourself how you ever functioned without a trailer once you get it filled with "essentials". It is true that you will sometimes wish you had a bigger trailer, but keeping it smaller does give you better mobility.
Can you see the trailer behind your camper while using your mirrors? The only time I can see my little flat bed is in a turn since I do not have a rear view camera. Typically, I advise people to match the trailer width close to the tow vehicle width so you can see it, yet it does not cost you much in additional wind drag. Also, matching trailer track width to the vehicle seems to help with stability on rutted roads. Some guys run reflector sticks off the rear corners of the trailer so they can see how it is tracking in their mirrors.
