We bought during a slow time of the year and we got a Fantastic Fan exhaust fan installed along with all the high-quality shelving my wife wanted installed (wardrobes and kitchen cabinets). We also got a factory "bonus" package that included a black tank rinse, power tongue jack, motion patio light, folding plastic patio table, and a few other items.
You should be able to get a number of things thrown in if your negotiating with a good dealer and sales person. We walked away from a young inexperienced sales person at another dealer on a previous HTT purchase. If the TT your looking at doesn't have these following items, I'd ask for them to be included:
Power tongue jack
Fantastic Fan
Black tank rinse
