We purchased a 2016 heartland 357 edge in October of last year. We don't do much camping where there is electrical hook ups so we rely on the generator recently we went to the campsite that have full hook ups so we went to plug in the cord and discovered that it is only 15 feet long is this normal on a 39 foot fifth wheel or did the dealer give me the wrong cord I've been trying to research this through the heartland's website and cannot find any specs on the shore power cord. I've decided just to purchase this cord but I've been looking on the Internet and they're anywhere from $100-$300 so not sure if I should take this back to the dealer where I purchased we also purchased the seven-year warranty would this be covered under? Thank you in advance for your reply is Steve Bill L
