Congatulations on the new trailer and welcome to the forum.
I am also towing with a Pathfinder, although my 2503S is about 1k# more than the 23LB.
Even though I'm near its limits I am finding that the Pathfinder is a great TV. At highway speeds fuel consumption is not great but on secondary roads, which I prefer anyway, it does much better and I can cruise along at the same speed as everyone else. (Also, I'm in Canada and we just don't have that many superhighways!)
From your photo it looks like you're using door mounted mirrors, not mirror extensions. I have extensions but the Pathy is not really wide enough to get a good view and I have to fix that.
How are yours working out?
Are you getting a clear view of what's coming in the lanes beside you?
Are the door mounts causing any damage?
I am worried about damaging the window or the window's seals where they hang on. If yours are working out I appreciate if you could tell me what brand / model they are.
Thanks in advance and enjoy your trailer!
