A 2000-2006 Tahoe or suburban would be ideal. The frames are strong, parts are everywhere, and i believe Cho/Richer Racing make a crossmember for put TTB’s on them. That opens the door to everything from cut and turned stock beams and 33” tires to fully fabricated beams and swing steering with fabricated uprights, hubs, and 40”s. For the rear you can have Deaver make a spring under setup and make a cantilever kit or poke 18” bypasses through the bed floor, or link it if you are trying to get the absolute most out of it. Suburban would favor a more traditional link setup since you could use crew cab spaced lower links and have the shocks mounting behind the rear seats. The wheelbase on those trucks is 116” for the Tahoe and 130” for the suburban, so they are fairly close to most rangers for comparison and drastically shorter than a crew cab silverado.
