New Trailer traveler - light weight, single

The big issue with light weight trailers is, there light for a reason. Small holding tanks, lack of storage, poor insulation etc. Can it be done? Sure. There are several youtube videos from people doing it. But it seems these people are minimalists to begin with. Personally I like my creature comforts, like heat, light, and ample refer space to have more than two days worth of food. I really hate grocery shopping.
As far as the rest? Buy a boot and a hitch lock.
Expect fuel economy half what you get now. That basically holds true whether your pulling a 3000 or a 10,000 trailer
