Hi, I just bought an Elkridge express e26 and because of camping time contraints I needed the fifthwheel within the next few weeks. The dealer was able to obtain an e26 that is currently on the line with all the options I wanted except the elkridge express e26 already had the heated and enclosed underbelly added as an option to the fifthwheel on the line. I was told I had to pay a little extra for this particular fifthwheel as it was already on the line and had this option. I cannot find this option available anywhere for the Elkridge express line of fifthwheels. I see it is standard for the regular Elkridge line of fifthwheels. Is this a new option for the 2012 Elkridge express line?
