I like the lift you fabricated! (and the storage aspect is definatly a plus).
that said... I'm an out of shape almost 40yo soccer mom. I take mine on and off a lot (on to go muddin 2/3x a month, off for a DD). By myself. Hey, if I can't get the door off, I'd be screwed if I needed to change the tire.
What has made my life easier: put some penetrating oil (I use AntiSieze, love that stuff) inside the hinge before you put em back on, they will glide right out. If I'm working with a tweeked back (like I said, old and out of shape), I use a 1 ton floor jack. veeeerrrrry slowly, if it catches at ALL I back it down and reposition.
And to get the doors to the backyard I use a walmart skateboard with oversized "off road" tires (which has moved sheds, beer fridges, ect lol).
Anyone have any tips on getting the power window/lock plug to disconnect easily? I have to crawl down and talk nice to it each and every time, it never wants to seperate without a struggle.
