Thanks Robb. Little by little. Now if I can keep from buying these old Chevy's, I would likely be moving faster on this project. LOL
The backup light were from, http://www.ddmtuning.com/Products/LED-Work-Lamp It's the 116mm version. They work great. I got the flood version.
As for the TireGate, it has been working great!!! I too want to build a custom rear bumper but time/funds have not been there. I needed something and this looked to be a good "temp" alternative. It's been working well enough that it might be "temp" for a long time, likely until the point I swap on the flatbed. Done a couple trips with a bunch of wash board trails and it's still tight and secure. It has a wedge lock plus the pin, so it gets really snugged up. For my app. it happed to fit very tightly to the bumper so I am sure that has helped. No rattles but with the Cummins, I don't hear much of anything else anyways.
The hitch part rated at 750 lbs. tongue weight and 7,500 lbs. tow weight. I was a little nervious at first when I hooked the car trailer to it but it worked perfect.
About the only minor complaint (and most swing outs have this issue) is there is no "lock" to hold it open. You can snug down the pivot bolts to put drag on it but if on a steep enough angle, the swing out will find it's natural open point. It would be nice if it had a couple stops it would lock into, for hills and such.
I was lucky to find mine on Craigslist. Not sure I would have spent the full price on one but after having it and seeing how well it's done and weight rated, I would be more likely to pay full price. If you didn't need the hitch to be used and could weld, you could build one for a lot less.
Hope that helps.
