We also have a Purpleline, but we have not installed it yet. At the time we got it, we were storing our RP-179 in a facility that had very tight quarters. The space between parking stalls was almost exactly the length of our tow vehicle. In order to park the R-pod, we had to unhitch, reposition, and re-hitch usually about twice to get the R-pod into the space. It took over an hour each time. That's when we made the decision to get the Purpleline.
Before we installed it, we got a different place to park the R-pod, which is a bit challenging, but not nearly as much as that storage facility. I can now back the R-pod into position pretty much in one go, and the incentive is less to get the Purpleline installed. We will probably get it installed this summer, as we have envisioned going to a few places where getting the R-pod into some of the spots we've seen could be a bit more challenging. We think it is a good investment.
