OK, thanks for the confirmation. I connected the sticker one time to try the system but due to heat, the sticker fell off. I'll put one again with double sided tape this time.
Yes. Oh ok, mine uses just the sticker but have not really tried it. Also, my question was for both the PPOB and the trailer 7pin. I guess you can do that while travelling.
Thanks for the response! Yes, I was also reminded by the guy in parts. However, he did say that if just adding a little bit in the resevoir, no need to dilute. ?
