Just got one!!! a 2720sl

I just bought a 2001 2720sl from some very nice people in Kennewick, Washington. Going to pick it up this weekend. I got it for $4750 and it is in very good condition. I am getting my Ford Explorer ready tomorrow for towing it. I have the hitch but that is all. I need the brake, power, sleeve, ball, etc. I am paying a professional about $300 for all those above mentioned things. I would just like to know if you think I got a good deal. I think I did, but since I have never been camping in my life I need to know. By the way, the people we bought it from were awesome!!
