Most Popular 3-3/4L x 1-13/16W Inch for Tiffin Allegro Bay Motorhome

These were really easy to install. I found that I needed more markers on the side of our 5th wheel trailer (44') I actually posted a few videos of people turning into our lane thinking they had passed the trailer. Connected to the rear and front marker lights and I have had no problems since.

Rather late in being delivered, but I wasn't in a hurry. Have not yet installed them. I would definitely order from etrailer.com again.
