I have the 2014 UB Vista (LOVE it!!!). We are planning to wait for a few years before we try for another child (DD will hopefully be 3-4 when #2 is born).

I am wondering if I should try to get the rumble seat and/or piggyback board now before they are gone forever (I don't believe the 2015 models fit the 2014 stroller).

I realize it is a long way off and a lot could change by then, but I'm worried I'll have regret if I don't get them now and then can't find them when I need them! And maybe having them would make selling the system easier after we're done?

Advice?
