Product review (1 stars): barely designed well enough for static use, i.e., not RV use
I bought the SR70F-U1 because my brothers recommended Engel. He has the older top loading Engel but they stopped making the top loader model.  So I bought this one.

I've used this fridge/freezer for about a year. I installed it in my 2016 Mercedes Benz Sprinter this spring (2017). There are two main reasons I'm disappointed to the degree of a 1 star review.

The nylon keeper on the back wall is too weak to hold the shelves from sliding forward. When the shelves slide forward toward the door, the sidewalls diverge just enough to let the shelves drop out of their slots and they drop down. I can't put only light stuff on the shelves, because I can't put heavy stuff on the door shelves (read about that below) so I zip-tied the shelves to the useless keepers at the back of the compartment as a work around.

The second reason for the 1 star, is the door's hinge design. The door pops open when I am braking and also hit a bump, like rail road tracks. This has happened to me many times.  I've added three thick washers under the bottom hinge to try to counter the door's sag. Now if I don't put anything heavy on the door, it stays shut. (The door's spring-loaded keeper pin is chamfered for easy closing. It can be installed backward and that would make the door hard to close and very easy to open. I mention this to ensure the reader that I have not installed the keeper pin backward. For those who think I've got the spring-loaded locking pin in backward, I don't.) The problem is a function of the flimsy door frame and hinges. They allow the right side of the door to sag beyond the tolerance of the spring-loaded keeper-pin to stay engaged under moderate dynamic loading.

The other reasons I don't like this products:
- The plastic shelves on the door bend and they fall off the door. They didn't get the tolerance right. The plastic shelves don't securely engage the door.
- The plastic tray under the freezer is too small and drops down.
- The freezer has no door so it's contents drop out the front and the back, i.e., don't stay in the freezer compartment.

The interior just isn't designed for RV use on rough roads, specially if you have it facing forward. I didn't have that option based on Sprinter RV optimum human factor usability and space utilization.

It's compressor is loud because of internal sheet metal vibration, but I turn it off at night and everything is still cold in the morning. As you'd expect from Engel, it's a good thermal design - low Q..

I'm now looking for a replacement, and I'll use this as my very expensive shop frig, where it will naturally help spread the word. If anyone can point me to a better frig for a Sprinter, please advise in a comment below.

I posted this as a product review on Engel's site months ago, but it never showed up, so I'm posting it here.  I sent photos to Engel, so if anyone wants me to post them please leave a comment.
