Lets see if that pic works- I'm towing a 18' open Big Tex. Two braked 3500# axles.
I haven't hit 6000# yet, and I really don't think I will. Car's about 3000 even, trailer is around 2100, maybe a hair over so I'll call it 2150.puts me at 5150, plus probably 6-800lbs of wheels and tires and random other stuff... so I suppose I'm probably cutting it close. The fact that you and a few others have accidentally hauled 9k+ makes me a little more comfortable with butting up against that 6k limit, and I certainly would rather play a little with the car's limit and have safe driving habits, than to play with the trailer's limit. The bags, if they do indeed work, will be a very inexpensive, great upgrade to the rear of my X5.
Still not sure if I'll be able to get my bags in before I tow the car home on friday evening, so I'm thinking I'll end up towing without them this time around. I might find time, but it depends on how today goes. Car's all back together and running great, new seat in, seatbelts hooked up, and I really just need to adjust the shifter a smidge and throw the rear bumper back on, and it's ready to be loaded up. I do really want to bring it home today if I can, so that I can get both my X5 and track car washed before my first event. If that ends up happening, then I might look at doing the bags tomorrow after I give everything a quick wash. Otherwise, they'll be in for the next event in 2 weeks.
