I would start by saying our first pop-up was a Starcraft, the RT10. LOVED that thing! I actually sometimes wish i had it back but the hybrid fits us (my wife) much better. LOL! I looked at the starcraft 16rb floorplan and noticed it was 11" narrower than the Jayco x17z, while the unloaded weight was only 115 lbs more. I am not sure if there is a huge price difference but if there isn't that 11"s might go a long way for comfort. plus the additional storage cabinets. We have the x17z and often get in each others way on long stays and there is only three of us. If i am not mistaken Jayco owns Starcraft and until recently all were manufactured out of the same facility. Just my thoughts. Good Luck with whatever you decide!
