The "Big Rig Access" on the review field is a big help, but "big rig" means different things to different people. I drive a 40' and sometimes a 45' RV with a tow car. I'd love to see a menu where you could select the size of the rig you drive. Example:
I drive a: Motorhome | 5th wheel | trailer | NA
Length: 30- 35' | 36-39' | 40-45'
Tow car? Yes/no
I always try and comment that a park has easy access for big rigs, but then one could also see that I drive a 40' or 45' RV with a tow car. I've been to a few places where my 45' rig just didn't fit, but it was marked a yes for big rig access
