Thanks - all that sounds like good advice. Yea the towing capacity is 4500 so I'd be pushing it but it would still be under the limit. And you know what? For me, the short way *is* through AZ and NM ... though there are still some steep grades especially on I-17 between Phoenix and Flagstaff. But yea I would just creep along at 50-60 etc. It would probably also help if I went when it wasn't 100 degrees out, but I don't know how long it's going to be hot like it is now. Anyway, thanks again.
