Just a follow on for those interested.
The dealer ordered my IntelliHaul 2.0 Trailering Camera System by EchoMaster at the time of purchase and was able to get it less than a week later. I delayed the install another week due to a trip I planned. I dropped my truck off on a Monday morning and picked it up Tuesday at 5pm. The dealer said the install was "interesting". It was the 1st they completed but everything seems to have went well and I didn't find any damaged panels or wires hanging etc. Seems to be a professional install job. I would note that this system includes a wireless camera that is to be mounted on the back of my travel trailer. My dealership offered to mount that as part of the install but I declined. I'd prefer to either do that part myself or take it to my travel trailer dealer.
Functionally now I have a left or right side camera view with a safety banner stating to check my surrounding area that shows up on the radio display when I turn on the corresponding turn signal. This functions even though the trailer is not plugged in. The cameras have a certain level of adjustment that is completed by having the truck running with the appropriate camera activated. Then, using your finger on the radio display, complete a long hold (just like using a cell phone and moving icons) and then drag the screen around to where you want it.
I also get a black screen with a the same safety banner when I 1st put the truck in Drive. The black screen stays until your MPH gets above the set limit. I don't really know the limit, maybe 2- 3 mph. This feature would activate a front camera which I did not order. It would be nice if I could disable the black screen due to not having that camera yet but I think I will likely add this camera soon as it is reasonably cheap and seems helpful to watch closing distance while parking and accidental things left in front of my truck by my kids etc.
Here are my nit-picky annoyances with the system. If I'm honest the side cameras are a neat feature but only duplicate the same view of the lower mirror of the towing mirrors. The side cameras don't really give you a new view. The front camera is not included at the base cost (I knew this and bought it anyway). Last I usually make adjustments to my radio while at stop lights. I tend to switch through stations etc. My radio display is now black (with the safety banner) blocking the functions of the radio due to being in Drive and under the speed limit. You can switch back off the black screen (camera view if you have that camera) by hitting the home button on the radio. So just annoying to hit an extra button. The last is just a word of warning for others ordering the system. The dealership kept calling this the "Invisi-trailer system". I'm not even sure what the actual invisible trailer setup is called but this is NOT that system. That system is limited to a specific truck package and is hard-wired to a connector by the license plate. This camera system is limited by the radio but again is NOT the invisible trailer. This version is a wireless rear camera. I was very concerned the wrong parts would be ordered due to the confusion. Everything worked out great for me but just something to keep in mind because of the two similar systems.
Last I have not yet installed the back up camera but will for my next camping trip in May. I'll try to remember to update this post then as the trailer camera is the real reason I bought the system. I'll hold my opinion of if the system is worth the cost until I try the trailer camera portion.
