depends... you want GPS displayed or camera...
I have the Garmin dezl 770LMTHD Trucker version... with backup camera with 50 foot extension cable.
the 770 has features the RV version does not have.. and better built.
then I downloaded the RV stuff from POI Factory into the Garmin.. so I have both ... truck and RV...
I also have a backup camera for back of truck... Peak 3 1/2 inch
so I can see hooking up trailer an also see behind trailer. no signal issues.
other then getting on facebook.. why a forward facing camera..
50 years of driving... I have never been hit from the front.
