Towing with a grill cold front

[BBuechler]

I was wondering your thoughts on the usage of a grill cold front on my 2018 ram. I'm towing a 10,000 Lb 5th wheel starting out the day at -4 degrees reaching a high of 15 degrees that day. Can't seem to find any info in the owners manual or online. Thanks!

It shouldn't have a problem maintaining operating temps pulling that load without the cover. But there are also flaps that can be opened should you choose to install it and try. I'd start out with at least a few open.
The biggest problem I think you will have is the installation. The cover is a tight fit and is very difficult to install at those temps. I'd suggest a heated shop if you are going to put it on.

I’d start with all 4 flaps open and see how it does. Watch your coolant temps. If you’re getting to 210° on the flats then take it off, but I doubt you will.

It won’t be needed while moving on flat or inclines but will be very beneficial on declines, idling, and while shut off for short periods of time.
