Some things that you may look for are the Fall package, party couch, corian countertops, countertop extension and Liepert 5 function remote control. If your truck came with the fifth wheel trailer tow package there is a Reese Elite 18K and BW OEM hitch that drops into the pucks and gives you full use of box without any rails to contend with. Also you can opt for pleather instead of cloth seating at no extra charge, as was told by Sierra rep to me. Like was mentioned in an earlier post we opted for extra options as this was going to be a long term RV for us. Good luck in your shopping.
