Help with basemodel 570 purchase!!!

Hey guys I'm new to atv's. I've been riding them and motocross basically my whole life! I'm looking to buy my first tomorrow! I'm interested in the sportsman 570 base model but my concern is the machine weighing 700lbs and not having esp. should I be worried? My main purpose for it is riding around my camp and some occasional trail/dirt road riding. Any help would be greatly appreciated! I'm only interested in the base model because I feel like the dealership is giving me a good otd price on a 2018 ($5480). Also would I be able to plow snow with it?

Differential seals

After my last ride i knoticed my 2015 outlander 800 xmr developed oil leaks where the cv axle goes into the diffs on both left and right sides both front and rear diffs. Not sure how it goes from no leaks to leaking at all 4 points after a ride but okay. My question is which way do the seals go? Do i have to split the diffs open or can i pull the axles and change the seals with the diffs still in the frame
