Hi ya`ll. Just joined the forum and I have a newbie question for you. I just bought my 2010 Titan LE crew cab 4x4 and then bought a 15 ft ultra light TT. It seems to pull ok on the straight-aways but going up a long hill I have to shift it down to 3rd or even 2nd to keep it going 45 or 50mph. And it really seems to struggle. Even though it`s an LE it still has the towing package (tow mode, manuel shifting,receiver hitch and electric set-up). The trailer is only 3500 lbs fully loaded. Is this normal for the titan. Every body else I talk to says that a 1/2 ton p/u with a 5.6 V8 should tow it like it`s not even there. Am I just expecting too much from the truck.
