Yep 10 grand is about right, and that's not including interior (or paint if you need it). My Silvy had 10 grand in work to lay it out, 8 grand in paint mainly because he changed the entire color, and 6 grand in billet wheels. The PO waited over a year for the shop to get him in, a year for them to lay it out, and the painters took 6 more months because they completely disassembled the truck for the color change. When people talk about laying frame or laying rocker, usually they don't know what they're up against. That's why you see so many poorly done jobs, because people want it done fast so they cut corners.
@RubenDLT have you looked into what kind of a rear setup you're going with? There's a few choices but only a couple that are worth doing IMO. Mine has a 4-link but there's more than one 4-link design. Your stock gas tank will have to go in favor of a fuel cell either way since there won't be room. Here's a good article on rear suspension types.

One of the issues with an SUV obviously is they can't just pull the bed off to work on the frame and rear suspension although they can cut the floorboard out. Which has to be done in order to install tubs. If you're thinking this is something you can do yourself, especially if you think you can do it on a part-time basis, think again, unless you're a really experienced fabricator. It's an incredible amount of work. And as for the front, if you want to tuck anything bigger than a 22" wheel, you'll have to tub the firewall which interferes with things like heater/AC etc. It takes extra work if you want to keep those luxuries lol. You'll have to relocate things like your fusebox and coolant overflow reservoir, etc regardless of the tub size and your hood springs will have to go bye-bye. Get used to a prop rod. You really have to want it if you're going to do this, and if you try to shortcut it you'll just end up with a pile of scrap metal. Good luck with whatever you decide. Here's some shots of my Silvy as they were building the frame and the final product. I'm still working on it, always seems to be something more to do.
