Nice work on the trailer. Not sure how I haven't seen this one before now. Your rack/tent lift is VERY similar to what I did on my trailer. Do you find that the cable in the center of the trailer to pull the rack down gets in the way of loading gear in the trailer?
Funny, I thought the same thing when I saw yours. Honestly I was probably perusing threads on here years ago and read yours, forgot about it and subconsciously channeled your build when thinking of mine. Anyway, to answer your question, not really. Given the width of the a2, I can put large tubs on either side of the cable and it doesn't get in the way at all. When it comes time to haul something large, it kinda gets in the way, but if I really need to I can just undo 2 bolts and remove the pulley altogether. I've thought about moving the winch to the underside of the trailer and replacing the pulley with a fairlead allowing me to crank it down almost fully out of the way. Eventually I'd like to go with linear actuators on all 4 corners and will ditch the winch but it works pretty well and as long as it's not getting in the way too much I'm not in a big hurry to replace it.
