My current project is building the ramp door patio railings and step. I'm about 90% done and figured I'd post a pic of it. I'll add more pics during the progress. In the pic below, I'm test fitting...
ORbiker, Yes. I'm familiar with the type you have.
We had the cables on our last TH, but didn't care for them. Of course, we didn't have the patio deck railing option.
I had previously planned to add the cables. I did purchased the railing corner mounts and the cable attaching links from Lippert, but decided on building the ramp-door jacks instead.
Below is a pic of our Jayco Talon with ramp-door patio cables.
