I have a 3 seat p1k and i live in arizona and its summer, my first ride with no roof no windshield and no modifications in a 110* day was unbearable,thought it was the worst mistake i ever made compared to my RZR 900 2 seater which is no gem either in heat but was liveable. the first thing i did was go to home depot and buy a roll of foil back insulation that everyone talks about and fitted it so the heat goes behind the seat and and up in front of the bed, this made it very liveable went from a 10 down to a 5 but you five seater people are going to cook your rear passengers. all machines have issues my friends rino with roof and full windshield is just as bad. i have a roof now and it is still very acceptable but not great but im riding in 100* temps ill put a windshield on in september when it cools off a bit im sure it will be a bit more noticeable all in all i love this machine.
