Many Haloview cameras solve the weak signal problem. I installed the Haloview RD10. I suggest the Haloview model you select should include a transmitter. This is placed near your truck. I have a very strong signal even though my camera is 50+ feet away from the screen I look at. You always want your lights on when towing. Since the rear view mirror is useless when towing anyway, the RD10 easily snaps on it... plus it's very natural thing to look there AND I don't have something new on the dash. If you pick another model, just be sure it's got the separate transmitter.
