if the invoice shows drums that is how it came.
do you know the build date for the unit?
discs became an option later in the 05 production.
mine was built mar/april and was a very early disc brake unit.
the disc brake option added another 2-4k$ to the sticker depending on axle count.
axles were also uprated so the late model 05s have a higher load carrying capacity...
toward the 05 year end all classics may have been ordered with discs...
so check the build date. if before march 05 these changes are unlikely.
as for the 'limited' package, search 2005 and limited. there are many posts on this issue and a couple that detail every item in the limited upgrade. along with long exchanges as to the value of the total package...
as i recall...jackets, hats, burgundy awnings/trim, acrylic door handle, larger lp gas bottles, hickory woodwork, solid wood tables, gold bathroom fixtures, electric jacks (std with slide units already), a flag box, matching zip dee chairs and a few other bits.
i like both the discs and the ltd woodwork.
all 05 classics came with the 5 spoke alcoa wheels; much nicer than the current stock wheel.
all of the true things that i am about to tell you are shameless lies. l.b.j.
we are here on earth to fart around. don't let anybody tell you any different. k.v.
