I have a small, lightweight trailer that I am able to move around by hand. Its been real handy; extremely versatile, for many years. I just did a modification to it to make it even MORE versatile. A selectably tongue length. The mod works GREAT.
Which added 30 lbs to the tongue weight. What's 30 lbs? Its still movable, at my present physical condition, but just not as far and requires smoother ground etc. But I've moved it plenty of times, even partially loaded. Often it's faster to unhook, turn around and reattach than to horse it around with the truck - certainly in the dark. Theres a distinct advantage to lightweight and paying attention to NOT adding unnecessary weight because burly eqpt can cost you in other ways. And its every time you use it. Whenever you decline to use it cuz you don't want to lift it, thats a cost too, its called "loss of use".
Having a welder, I'm often inclined to go lightweight for its benefits because I always know I can either brace it if it needs more or fix it if it "needed more"
I understand lots of folks can't work like that. Welding less than 4mm is near the lower limit of stick welding so many folks, if not real confident, prefer thicker materials to make sure they don't burn holes.
In any case, moving that socket to the corner sounds like a great plan. Plus you'll get to grind off those ugly welds. Gotta wonder why they didn't put it in the corner. Agreed maybe it was tipping a small tractor.
