Dually Truck.. What is this feeling?

I am a retired auto mechanic... worked on cars and trucks for years.(43)
in 2005 Purchase a New Ram 1500 for up coming retirement.
(never owned a truck before)
fast forward to last year.. change of program..

purchased a 2012 Ford F 250 and a 30 foot travel trailer.

here is my question/issue..

What is the feeling/desire/strangeness... for a Dually truck.
not needed.. and 8,000 pound trailer is fine with the F 250..
and will never be in the budget!!

Current Ram looks great.
Chevy is Nice .. except for odd shaped fender wells.
Ford.. not so nice rear fenders..

I have never had this feeling (or whatever it is) in my life.

maybe mid life issues at 65?

Thank You .. may need to see a doctor .:)
