From 2006 to 2014 we had a 33.5 foot Montana. Kind of cramped. To get to frig,the recliner (me) had to put the chair back to upright for wife to get to frig. Loved the looks of the 3400 back then. So I got a Mountaineer that is 37 feet long and has the same layout as the old 3400. We love it.

As others have said, there are a few places (especially NP's and govmnt parks) where we don't fit. And as others said, I look online and if not sure, call and tell them I want a pull thru and my length.
A bit of good news for me - Yellowstone Fishing Bridge is upgrading and will have longer sites (maybe pull thrus, I can't remember) next year. I stayed there once with my shorter rig and had to drive the front of the truck into the brush at the front of the campsite in order to park and also leave.
