A great ride and extremely useful. Very good gas mileage for a it's size (25mpg). Extremely roomy and the built-in air compressor is very handy.
The air compressor was indeed handy on our 1998 Pontiac Transsport/Montana, as it provided an on-board tire pump for whatever we needed, especially bicycle tires. But it was a bloomin' nightmare for not knowing when to shut off when it was levelling the vehicle. The back end would begin sticking up on the road, and the van would ride violently for several minutes. The seat belts would be all that prevented the children from being thrown out of their seats.
Repeated complaints from us led to the levelling sensor being replaced, which brought relief for six months. Then it started doing it again, and repeated trips to the dealer "we couldn't find anything; can you bring it back when it is doing it?" failed to solve anything. A call from GM merely informed us that they had never heard of the problem. We had a garage disconnect the pump.
