When I first started looking at the Heartland MPG trailer, the one that I really liked, and ended up purchasing, did not have an external radio antenna. I asked the dealer rep to find out where it was and since the radio did work, we both assumed that it must have an internal antenna. Well, while on our first "shakedown" camping trip with the trailer this past weekend, I noticed that the signal reception on the radio was not that great. So I took it upon myself to remove the two mounting screws holding the radio in the cabinet and found that the factory or dealer had installed a ribbon antenna (still all bundled up) behind the radio. I also noticed in the factory packaging, another wire antenna. So I exchanged the ribbon antenna for the wire antenna and the radio reception greatly improved. BUT, where is the external antenna that should have been installed on my unit? I figure the factory FORGOT to install it, so they conjured up an alternate fix. I was not too happy at what I had discovered on my radio. The ribbon radio antenna I am speaking of is the type that you used to install to your home stereo that would be mounted to a wall and spread out (looking like a T). I am going back to the dealer today to ask them about this and see what they plan on doing about it. The shakedown trip did find other little fixes, but nothing that cannot be fixed my myself. The bed definitely needs some help with a nice foam pad. I have also purchased some additional supports for the front of the trailer's frame. Without them, there is some wobble inside the trailer. The trailer towed nicely behind my Ford F-150, but I think I still have to tweak the brake controller a little more. Other than a few things found, I can say that we are totally satisfied with our new Heartland MPG 181 and plan on taking more trips with it soon.
