Seeking advice on Dometic vs Engel 12v fridge

I'm posting this question here as there has been no response to my post in the Gadgets & Electronics forums, link below. I think I'm going to spring for a $700-800 Dometic or Engel fridge after decades of limping along with my Coleman 40QT. I'm pretty sure over that time I have spent nearly $500 between the cooler $99 and several new power cords every year and replacing the fan once or twice.

One review for the Dometic says it's susceptible to RF interference from CB/Ham radios and gives instruction on how to install ferrite chokes on the power cord.Supposedly the CB RF scrambles the Dometic microprocessor. I need some real-world verification if this is true.

I've settled on a COOLER STYLE fridge over a dorm fridge or built-in truck fridge since on occasion I have to swap trucks and I ALWAYS eat mostly out of my cooler.

Any problems with Dometic fridge and CB/Ham radio transmitters?

 

My 40 qt Coleman already takes up about 90% of the space between the seats in my Freightliner. At least the Dometic or Coleman will keep my food cold instead of just below the temp at which I must throw my food away.

 

I was considering the Dometic 40qt until I saw it at the Petro north of Birmingham. The exterior is about the size of my Coleman, but the usable interior space seems much smaller. So I'm looking at the 50qt, not the 65qt with fridge & freezer section. I don't think the 65qt could fit between the seats in my 2018 mid-roof Freightliner. That's the only place I can dedicate to it, I've tried all other locations . Thanks for reply.
