The trailer you mentioned is definitely light enough for your truck. I'm not very familiar with Chevy performance but it should do just fine. Of course, lotsa folks here will tell you anything less than a Freightliner Sporthauler is unacceptable. Hopefully someone with the same/similar truck and trailer combo will be able to give you the info you really need. I do know that my Ram 1500 5.7 hemi wouldn't have any problem at all with a 6,500 pound (max for the Apex 235). Wind resistance is going to be more of a factor than weight when you see the really low MPG numbers.
At some point during every day you suddenly realize nothing else productive is going to happen the rest of that day. For me, it usually occurs around 9 am.
