I am replacing the slide seal on my 2017 Bighorn. The existing seal is a "double sweep seal" shown below in left pic. It's a single piece that wraps around the exterior wall with sweeps inside and out. A 96" piece of this original seal is $400! I found a single seal on Amazon for much cheaper at $45 for a 10' piece - see right pic below. It seems that I could buy two single seals and install on inside and outside of the slide and it should have same result as the original double sweep seal. Anyone else done similar repair?
