I've put my frontier to the test and i was impressed with it towing abilities. I pulled my new 6000lb 33 foot RV 450 miles, and my frontier is still alive. I was able to maintain 65-70mph in 5th gear while getting 9.5 mpg. The trip was 90% level ground, and the hills slowed me down a lil bit. I dont plan on pulling this thing often so I have no need to upgrade to a titan. Nissan makes a damn strong truck.
