Many of my friends have class A rigs (with and without towed vehicles) and It seems that my fifth wheel is as manuverable or more so than the large class As are. I have been able to get into some sights that a class A could never turn into. On a level surface the 88 degree offered by Heartland comes in very handy, and most tight sights are not that tough with a spotter and some practice.
Enjoy your new toy!
