I have a 2016 pioneer 1000 5 deluxe ! All and all its a great family machine thats why I bought it! Back seats are roomy but not very comfortable, I have 140 hrs on it now and not have had one issue but I do have to bring it in for a clutch recall! Machine is very smooth shifting only complaint would be reverse is too high of geared if ur stuck u will notice it ! otherwise a non issue! Also lots of heat from engine comes up into cab but there is a recall for that too apparently they put some heat shielding under seat but I havent had mine to the dealer for that yet!
Nice to have the box if u dont have any rear passengers it will fit alot of gear! seats fold down with a hit of a lever same with the dumping box! Good unit overall !
Another 4 seater that I would recommend is the kawasaki teryx 4
I heard the first year had issues with the clutch wearing out fast or having issues. Might have been a recall on them to? But most guys really like them.
