All I can tell you is that Lance is a more expensive overall product than Palomino. It's been a few years since I looked at any new Lance TC's, and even longer for Palomino. A lot can change in a few years.
Looks like Joplin is the closest Lance dealer to you. The one I knew about in OKC is apparently not a Lance dealer any longer.
Have a look through
RVTrader and be prepared to make a trip or two.
Actually, it's to your advantage to buy a new one out of state. Make the proper arrangements with the selling dealer and you'll pay no sales tax to the dealers state, and since OK doesn't tag or register TC's, you'll pay no tax to them either.
Or, buy a nice lightly used one from an individual like I did 10 years ago and get a better price and no tax. I didn't see my camper in person until the day I bought it. The previous owner sent me lots of hi-rez pictures, so there were no surprises. I was happy with what I got, and I still own it.
There are some parts of the country where TC's are VERY popular, and that's generally where the big TC dealers are, and where most of the used units will be.
