I made therse rock sliders for my buddy's Tacoma. We used 1.5" square tubing for that bulky, industrial look. I think they turned out pretty sweet.
And here is a pic of me welding them on...
great looking truck and great looking sliders. What thickness did you use for your metal? How many legs connect it to the frame? THe only issue I see is using a hi-lift with the sliders: the jack will be resting on a point/corner of the slider rather than flush on a flat part. But it looks great! I add skateboard grip tape to the top of mine for traction in the winter. Then again, I'm short and I need to step on my sliders to get in my truck.
Is your buddy on RME? We have some cool upcoming trips I think he'd enjoy.
I've never kept a car for more than a year and a half, but in the past, it's held up REALLY well and didn't show any signs of coming off. It's really grippy the first week. Just make sure your passengers don't get used to sliding their legs down the side of your slider, they'll tear their legs up.
The tube thickness is 0.120 hrew. And there are 5 legs conecting it to the frame. It is plenty strong! The sliders have the rust oleum spray bed liner so the traction is pretty good.
Grip tape or bedliner is awful IMO on sliders. Once you drag the back of your leg or calf across it in shorts you'll realize what a mistake you've made. Your seats will like you a lot better without blood all over them. lol.
