I have the one below. I purchased it when we had our previous camper and moved it to the new camper. I also purchased and installed the side cameras on the previous camper. Personally, I wouldn't spend the money on the side cameras again but mainly because with our new truck has mirrors that extend outward, and I no longer need the side cameras. With our previous F150 without extending mirrors, it was harder to see the sides so the cameras were helpful. Also, I opted for the 5 inch monitor to save space in the old truck. But I think I would opt for the 7" if I did it again. The 5" works fine but if you have room 7" would be better; especially if you want to get side cameras. Hope that helps.Could you share what vision works system you have? I’m looking to get a backup camera for my Husband to put on our trailer and I have no clue what I’m supposed to get.
