My opinion is a 94 Class "C" without a built in generator is a $4,000 - $5,000 motorhome. A Ford 460 will tow a 3,000 lb. trailer without much problem but you will need a brake controller and verify the tow hitch is rated for that much weight. If you are riding motorcycles you will probably be boondocking which makes the generator practically a necessity. You can buy a single Honda 2,000 but that probably won't run the A/C in an Oklahoma summer. Probably need two so figure a minimim of another $3000. The small solar panel is probably sufficient to keep the batteries charged when not in use but not much else. Better to look for a $5,000 to $7,000 Class C wth a "working" built-in generator. If you don't need the A/C it sounds like a decent vehicle but $10,000 seems steep to me.
