@RinconVTR, WDH is a must. I have an E2. The "dreaded axle issue" is supposed to be resolved in the 2014 models. I will still be keeping an eye on my tires. So far over 600 miles and no wear (knock on wood).
@svpetty, sorry for not responding sooner to your reply but, we've been camping!! LOL!
You are correct, the axle on mine is a GAWR 4000# axle.

And yes, the ground clearance is more (possibly 4"). I will try to snap a picture of the TV mount and arm for you as soon as we get back. AGAIN!!! LOL! It's attached to a cabinet in ours, not a wall.
