The 210WBS that we ordered, optioned up and with full LPG tanks and battery came in right at 3740 lbs. Since we are retired and go for months at a time, we tow heavy. Always empty tanks, but, I pack enough tools to build a TT and with all the cat food (cans) and our accessories (she weaves - we even take a spinning wheel), bicycles on the back, etc, we come in just shy of 5900 lbs. loaded, just about the max on the trailer's loading.
Your V6 has the power, for hauling, though on the hills you'll pay... You are far more likely, though, to exceed the "load" limit of the truck if you aren't careful. The truck's load capacity is calculated with a single person (the driver) at 150 lbs. You have to figure everything that goes into
the truck; options, passengers, cargo and hitch weight. At a tad less than 6000 lbs, my hitch weight is ~728 lbs. give or take. Utilizing a WD hitch, I'm transferring about 25% of that back to the TT axles, which means that just by hooking up, I've dropped the equivalent of ~550 lbs into the "cargo area" of the Jeep. Like stacking a pile of cinder blocks in the back seat area... While my Hemi V8 is way more than qualified to tow my TT's weight, I'm right at the load limit (weight of the tow vehicle). That's what you'll need to be concerned with...the total weight that the truck is carrying
, not so much as the weight it is pulling
... You definitely have adequate horsepower, but, you need to keep an eye on the capacity of the truck's frame, suspension and tire loading.
As an aside...most "towing capacity" is calculated using a flat bed utility trailer with the "weight as specified", i.e., my Jeep is rated at 7200 lbs of flat bed utility trailer weight...much different than pulling that weight in the form of a flat faced travel trailer. A lot of companies will also specify a "sail area" capability, like 6x6 or 4x5, to allow for wind resistance. As the square footage of the front of your trailer increases, the amount of horsepower needed just to defeat wind resistance also increases. I've towed 6800 lbs on a utility trailer with my Jeep...it pulled much easier than the 6000 lbs of my FunFinderX just because of the lack of frontal area...
