Well thats a toughie really. I know Cyclone is Heartlands top tier TH. However They are very problematic. We sell lots of them for sure, we get every one of them back (over and over and over again) Actually "right now" on our lot for repair, we have 5 Cyclones. Only have 6 5ers and 5 are Cyclones. The 6th 5er is a Cougar with an inop Suburban furnace. The Cyclones have a laundry list. 1 has 127 line items, another has 52 items. One just has one problem - 5 different spots of delam. The other 2 just a few minor things that we should complete by weeks end.
The only Forest River product we sell is Coachmen Sports Coach DP. We do service everything though, and as a general rule, we get more Forest River repairs than we get Heartland, but Cyclone is our exception, without Cyclone, we wouldnt get hardly anything from Heartland.
Having very little experience with Vengeance "most common" problems, and a firm understanding of Cyclones biggest problems. ---- I would buy the Cyclone still.
