panman,
Wow, a lot of questions. Good. I like to see that. As for your first two, the largest RFM that I know of for the 2210 is the 272, or 72" and the 210 loader is rated for 620 lbs, but trust me, with proper ballast, it lifts waaay more than that.
It seems to me that you're about at the try me out stage. Why don't you do that -- preferrably on your property -- and get a feel for what is really important to you? /forums/images/graemlins/tongue.gif
