Joe, have had both.
All you need is a 2500 with 2wd, big engine and transmission to tow the trailer safely, big brakes and a great trailer brake controller come with.
Diesel is better and a matter of choice and pocket depth.

Would recommend paying up for 4wd.

When your trailer is sitting on grass for a few days it sinks in the turf more than you would like. Add some rain or dew the first move to pull out of the ruts can cause the drive tire or tires slip (if you opt for locking diff which you should have with either) the next move clogs them and you are stuck. Been there done that......... Highway tread tires are a culprit, all terrain may be better, dual rear wheels may.....

With 4wd before even trying to move put it in low range 4wd and 1st gear and just drive off the grass on to solid ground put it in 2wd and enjoy the AC on the ride home.
