Looks like Tim's XLR is the same set-up as our Vengeance's. Not sure how the 29HFS set-up works or if its different.
As for unloading, you pull the pins holding the cable to the ramp and the ramp goes to the ground. You have to let the patio rails hang out in the air free. That back part of the rail folds in. Its not recommended to leave them out there for an extended period of time because the weight may cause them to sag over time. But leaving them hanging long enough to load and unload toys is no problem.
Mine also came with steps. But quite often, we don't take them with us. We actually have two patios and we rarely use the steps enough to make them worth the trouble of hauling them in the garage. They just get in the way back there.
The steps are super quick and easy to remove and install.
