I am kind of partial to the 02 Pace. Had mine since spring of 2010 an have not seen another gas coach I like any better. Two things, one of which was already mentioned.
1) Check the tires. I didn't, and mine had the original rubber on it. That gets expensive quick when just starting out.
2) This Pace has a lot of overhang on the rear and don't try to redesign the back end as I did by forgetting about the W I D E tail swing. I found out just how stout my 4x4 mail box post was.
The jacks were mentioned and you have no lack of power there. Here is a picture of my second outing with mine and being the novice I was I didn't know it is not a good idea to lift the rear wheels off the ground. I was just out to level the coach. Well, when I got out to look I found the right wheel was about 2" off the ground. I didn't even realize that when I was leveling. On level ground those jacks will pick all 4 wheels off the ground. I just wanted to see if it would do it.
I'm no help on the Ford chassis since mine has the Workhorse W22 under it.
Oh, it also has the Norcold 1200 fridge that has the recall on it. Make sure that has been completed.
With the condition of that Pace Arrow I think the price is not too far off. May be a little high so the -$5K might be worth discussing.
