X2 on the step back and take a breather. At this point, patience has been officially lost. On that same note, you'll have a hard time getting the price you're asking for in it's current condition.
Some tips I don't see mentioned...
Welding takes practice and patience, especially with sheetmetal.
Measure twice, cut once. And with that comes a lot of checking fitment, adjusting, checking fitment, adjusting, checking, adjusting, and so on and so forth. Until it fits right. Especially with cheap LMC replacement panels.
This is a wheeling rig, right? It doesn't need to be perfect, just solid.
This is your first time taking on a project like this, right? Mistakes will be made, I guarantee it. All you can do is go back and fix them. The key to this is knowing when not to go too far so that you don't have to do the whole job over again.
OK, you mentioned your welds popping after you get them in. Not enough heat. You need more practice welding. Take the welder inside the garage/shed/basement/workshop and get some metal and start practicing sticking multiple pieces together. Take 2 pieces and stick them together with a couple plug welds. Then beat on them and try to pull them apart, see how the welds hold up to your abuse. Keep trying till you can't get them apart.
What size hole are you using in the top piece when you plug weld? 3/8"? That's probably a good size. What I like to do is start in the center of the hole and work the puddly out in a circle till it contacts the top piece and connects them together. This takes patience and practice to do it right. Too much heat and you can burn right through. Too little and it won't stick. Slow down the wire speed, try different settings, get it to a point where you feel comfortable sticking sheetmetal together. Then you can go back to the truck.
You may need to pull that panel out and start over. I'm just gonna throw that out there. What you have may be fixable but may be easier to start over. On top of that you seem to be missing the inner rocker panel which creates that pinch seam that the weatherstrip clamps to. My last suggestion, get whatever you need to finish it (new panels/more panels/flat stock to cut and make what you need) and get it all mocked up and fitted right before you make any more welds. Then you can start welding it in once it's all ready to go, and after welding practice of course.
Finish what you started, be proud of what you accomplished, and chock it up to a learning experience. Or sell it and go buy a Jeep and go hang out at the mall with all the other girls.

i remember doing heads and cam on my Powerwagon under the hood in the pouring rain for 2 days in the mud parking lot of the concrete plant I did resto's for.... ah fun times... 
floors?
So keep in mind it can always be worse. You could have my '73. Better go inventory the hammers and dollies and refill the gas bottle. Only good thing is I will wait till spring.
