Junction Box Replacement Recommendation for Trailer that Uses Cap Connectors for Trailer Wiring

Question

Question:

Hi I just wired in a new 7 pin cord to my campers front junction box. I am really not happy with what I see in that box. In particular, all of the wire nuts which are typical in these JB. Would this 10 pole box be a good replacement for that? I certainly understand my 7 wire connections just not sure how to manage the others. Im going to add a few pics to hopefully be of help. Thanks for any help.

Cap connectors are not the best way to connect wires. The Pollak 10-Terminal Junction Box # PK52248 would be a way better way to make the connections as opposed to what you have now.

I attached a picture that shows the junction box wired up next to the picture you submitted to show the difference. I also attached an install video link for this as well.
