Based on how cheap the one I got from the dealer looked I'm surprised you got a year use out of it.
I upgraded to RhinoFlex (15") a year & half ago and recently brought a 5" extension hose that attaches to the 15" hose. The extension piece wasn't much cheaper than the original kit.
There are several types of RhinoFlex hoses to select from. I got mine at WalMart but Camping World sells it too.
Depending on where you camp will determine how much hose you should be carrying. I've never needed more than the original 15" but at once CG I only have a couple inches to spare so I picked up the extension piece just in case I need it.
One of my beach cg here is getting full hookups in selected sites but they placed the hookups closer to front of the site (where the TV usually goes) instead of towards the back of the site. I expect I will be needing the extension at that cg. See pic below of hookups location.
Great choice for "Living within my means" and camping for one...
