Best Brand Roll Off Container/Dumpster truck for 35k

Long time lurker, first time poster. Long story short, I just recently got into the roll off container/dumpster business and am looking at purchasing another truck. I'm looking to spend roughly $35,000 on a truck and would like your professional opinion as my best bet. Before I get into makes/models/miles, I want to let it be known that I intend on hauling two 30 yard dumpsters/containers with the truck at hand; one on the truck and one on a trailer (I'm thinking of just towing two empty containers to and from job sites, while hauling filled containers one at a time - thinking this is best not to stress the truck?. This being said, I have found Internationals and Macks. Example on ebay - 1996 International Reveling Roll Off 4900/DT 466E Automatic Alison Transmission -220k miles- http://cgi.ebay.com/ebaymotors/1996-INTERNATIONAL-ROLL-OFF-TRUCK-CLEAN_W0QQcmdZViewItemQQhashZitem1c0d5a5df8QQitemZ120483110392QQptZCommercialQ5fTrucks

Or a Mack with roughly 100k more miles on it. What's the better bet? I know this is a vague question but damn these trucks are expensive. How many miles are these types of trucks good for? Issues to look for? Its late and I'm thinking outloud but any input would be greatly appreciated. Thank you for taking the time out to read my post.
