I have an '05 with the off road package. The window sticker is still in the glove box (bought it new), but I don't think there is any special suspension call out except red painted shock absorbers. I'll confirm later.

Other package features include a 3.91 sure grip differential, skid plates, tow hooks, 275 70 17 Goodyear Wrangler (noisy) tires on argent aluminum spoked wheels, and graphics on the box side.

It does sit higher than some other '05s, but the standard tire w/o the off road package was a 245, rather than the 275. The 20" wheel package was common on the Laramie, but I don't know what the section width or profile (ie height) was with that combo.
