I have a 2010 V6 Frontier. Love the truck. I used to tow my popup with various midsized SUVs and then the Frontier. No problem. I then upgraded my TT to a 26bh, no slide. It's about 5300lbs on the road. I use a WD hitch with sway control. But, it's just plain stressful. I can hold 55-60 mph on the flats but any kind of grade zaps me down. Heaven forbid I have an on ramp with a hill. Then, any semi's that pass you shake you pretty good. My stepdad tells me he had similar issues pulling his airstream with his avalanche. But, I gotta believe that with the larger engine and wheelbase that it's got to be better. I'm currently in the market for a full sized truck with a minimum towing capacity of 8000lbs or greater. I hope this helps.
