Mine was bowed from PO pretty bad. I ended up installing a tailgate lid from wagongear. It pulled it back straight pretty close to flat - noticeably better. There are several folks who make lids so it is worth looking around, but I was extremely satisfied. Kevin makes a great product.
I think your welds look great for a first run! I agree on the gusset for the tall vertical from the swing-out and actually a plate like shown in cruiserpilot's picture is a good idea. Take it halfway down the swing-out arm and it will help with front to back rocking.

I recently rebuilt my turbo and have been satisfied, but wishing I would have upgraded. I did a bunch of research here and the Grunter vortex green from G Turbo is pretty much a straight swap and it can run without an inter-cooler. If I had to do it again I would have upgraded.
My glow screen was working intermittently and has now quit altogether. Traced through to the screen connections so it is getting power but no continuity in the screen. Pulled it up on PartSouq and was able to source out of Japan for $425. Are these rebuildable? Any other less expensive options?
I had a great time meeting up with @turbotoyz this weekend (while observing social distancing and wearing face coverings) to pick up his RTT. It was in great condition as advertised and they helped set it up on my rig. I look forward to many nights with it under the stars.
Ditto what @bottombracket said. I have had them about 6 months but the best upgrade I have done to any of my cruisers. Wish I had put a set on my previous 62. I drive the mountain passes a lot over to Central Oregon and now I don't get headaches from late-night white knuckle winter trips.
