Welcome to the Solaire family. We looked long and hard at this model before deciding on the 269BHDSK instead. Both had very nice features. Especially liked all the outdoor storage on the 25BHSS. Enjoy!!!
As to what not to forget, I'd put at the top of the list everything to handle black waste. This includes chemical for the tank, good quality sewer hose, rubber gloves, RV toilet paper.
