I tow a Keystone 32FB with a 2007 EL Exp. The tongue weight is a bit high but if you pay attention to how you load it you will be fine. I have towed it roughly 6,000 miles in the 7 months that I have owned it and it has towed great. Even in high winds and pulling the Sierra Nevada and Rockies I didn't have any issues with power or feeling unsafe. You won't set a land speed records going up hill but I didn't drop below 50 pulling hills at about 3500 RPM. On the flats I ran between 70 and 75 mph depending on speed limits outside of CA.
Trailer loaded for a 2 week trip, 4 adults, 1 child, propane full, gas full, and 1/2 tank of water my weights were 3400 front, 4700 rear (500 lbs over), 7700 trailer weight. I did upgrade to 10 ply tires which made a huge difference both with and without the trailer. We pulled it from the California to North Dakota and back and everything worked great.
