Have you ever towed anything before?? That's an awful lot of trailer to break into the trailer towing game! ;)
And doing it with a 1500 Dodge Ram that will be maxed out pretty much towing that thing dry is going to be a definite 'pucker factor' event... ;)
Remember, the "tow ratings" assume an empty truck that weighs in at it's "curb weight" and from what I've been reading lately, the "curb weight" figures are a stripped down version of your truck and even has items REMOVED from the truck to get that low "curb weight" figure...
Anyway, I think you'll have your hands full.. Sure, you'll get down the road.. No problem with power with that rig... Handling?? Well, that's another ball game and one that might not be too much fun...
Good luck!
