Is height a concern with the Bighorns?

Hi,

I'm slowly closing in on retirement and one possibility I'm considering is going fulltime in an RV for ~5 years or so. There's many areas out west that I've never seen and would really like to take some time and see that part of the country.

Here's my question: I really like the Bighorn models (particularly the 3270RS). However, the height of 13' 3" concerns me (as far as hitting low structures, tree branches, etc.). Is this something I should be concerned with or am I blowing it out of proportion, especially since I would primarily be in the west and Midwest?

BTW, my experience has been with TT's and Class C's. Also, I'm 6'1" tall, so a mid-profile 5th wheel is a possibility, but I don't want to be banging my head.

Thanks for any help!
