Here's something if any of you are interested. I made one myself for my tent and they are easy and work great. No welding whatsoever and your main tool is a jig saw. It can also be used in your work shop or garage. The main ingredients are 45 gallon drums and i'm sure you guys see those things everywhere. Here's a pic of the one i made. If any of you do decide to make one, don't waste your money buying a door latch. PM me your address and i'll send you something that is 10 times better, stronger and is adjustable so that you can suck the door tighter like the one on my door in the pic. I have to say also that this isn't my idea. All credit goes to the author David Scott Mathews.
