That's a really nice system. However, ff you need something that is more portable, I recommend this setup : [link]
It is super light and portable, which is the main reason I bought it. It is strong enough for doing weighted pullups (Tested it with 135lb attached to my 200lb body). The downside is that you can't do muscle ups on it without having it topple over.
I was looking at these ones but the DIY one seems a lot better
just a superior design.
