RV Cam kit for 5.3 [2005]...what do you run in yours?

[Texas Red]

I have a 2005 GMC Sierra 5.3 and I tow a lot, sometimes daily. My mechanic is building me another 5.3 [i think it's a 2003 version] and am thinking about upgrading the cam. I've heard about the LS9 cam kit, but I wanted to see what you guys are running and how you like it. I am targeting around 375-400 hp on this one with just the cam kit, I already have a tune and true duals with Super 44s although I know I will need to re-tune for the cam. Don't want to have to change the torque converter as I have a brand new trans in it with converter, Corvette servo and shift kit already installed.

Mine's a 4x4 and I run 295/70 mud tires on it. Not sure if that matters, but I thought I'd mention just in case. Also not planning in changing the stock exhaust manifolds out.

So anyone been down this road here? Looking for cam kit suggestions....thanks for the help!
