The big weight adders are bathrooms. This camper has none. And it isn't a pop up or slide out or any of that nonsense, so nothing there adding weight.
It does have a 30 gal freshwater tank (for the little sink in the rear kitchenette area), and of course the 30 pound propane tank.
We went with this one specifically because it was light, it was not a "soft side" so we can camp in bear country, it does NOT have a bathroom/toilet, and it has a full sized bed that does not require you to step outside of the camper while getting out of bed. We looked at the little teardrop ones and my wife said she didn't want to have to get out of bed through a door on to the ground.
I do some ATV riding, too, and this was a nice size to pull behind my F150 when I have the Recon in its 8ft bed.
For what a T'reg would cost, I'd just have kept my Sprinter and turned that into a camper. We'll see how the Golf does on longer trips, but the couple short (less than 25 miles) I have done with no trailer brake controller and my cobbled together manually operated trailer lights didn't give me much pause for concern other than if I hit some severe crosswinds at higher speeds. I've actually towed quite a bit with this Golf over the years, usually my utility trailer full of all kinds of things (scrap, my ATV, lumber, firewood) as well as quite a few broken Volkswagens via tow dolly. It has never let me down.
And it actually pulls hills with a car hooked behind it easier than my F150 does. Go figure.
