Are these accurate specs? I was looking at these three models at a store here in FL while I'm visiting and in person, the 570 Mid size looks way smaller. The 570 Full and 900 Full seemed very close, but the 570 seemed narrower up front?

Spec sheet wise...

570 Mid: Overall Vehicle Size (L x W x H) 110 x 58.0 x 73 in. (279 x 147 x 185 cm)
570 Full: Overall Vehicle Size (L x W x H) 116.5 x 60 x 76 in. (296 x 152 x 193 cm)
900 Full: Overall Vehicle Size (L x W x H) 116.5 x 60 x 76 in. (296 x 152 x 193 cm)

570 Full and 900 Full are the same size?
570/900 Full are only 6.5" longer, 2" wider (looks like it's like 5-10" wider), and 3" higher (visually even higher due to the tires)

Maybe my eyes were playing tricks on me, but it certainly didn't seem like they were that close in size.
Also, interior room wise, the 570 Full and 900 Full were definitely more comfortable.
I'm not a super huge guy, about 6'1" and 200lbs, and in the 570 Mid, I was banging my knee on the shifter whereas in the 570/900 Full there was room to breathe.

I have a 2015 Midsize 570 Crew EPS and it measures 59" at the outside of the rear tires (the absolute widest part of the machine). I'm betting if you measure the 900 or the 570 Full-size, it's over 60" at the rear tires, possibly 62-64 inches. However, the main thing is to buy the one that best suits your purposes.

I think, if you aren't considering price, the 900 Full gives you more HP and a few other add-ons in the same size "package" compared to the 570 Mid.
The 570 Mid gives you less HP but in a smaller/lighter body.

I like the concept of the 570, the only peeve for me is the smallish cab compared to the 570/900 Full.
Plenty of side to side room, the problem is really the leg clearance, even getting in and out I banged into the side.
I mean I can deal with it, but if the 900 will fit the trails (again not considering price), that may be the better direction.
