Buying my first sled

Hello all, I'm buying my first sled in the near future and was hoping for some advice. The sled I'm looking at is a 2006 Polaris Switchback FST 144. It has 1.25 inch paddles. Dealer wants $3600 for it and it has 4228 miles. I'm a larger guy, 5'11 270 and I want to know if this would work okay for me. I want to spend some time on the trail and in powder. The off trail stuff doesn't get gigantic in the winter, I'd say 4 ft deepest and I wanted to know if this would be okay off trail. Both my buddies are getting brand new Ski-Doo Freeride's with 2.5 in. paddles and a 153 in. track but I don't have that kind of cash to throw around, I'd say $5500 is the most I'd spend. I just missed out on a 2008 Arctic Cat M1000 162 that had 1800 miles on it for $5500 so I would love something like that too. I personally think the Switchback would be okay but I wanted y'all's opinion. Thanks in advance
