Fumoto valve is one of the best investements I have made for my truck. If getting the filter off wasn't such a slippery mess I would say I almost enjoy changing my oil. Gallon bag works pretty well, but I still always seem to spill a little.

I always just change mine at my convenience between 10% and 0.

I will also recommend the Fumoto valve. It is like opening and closing a tap for draining the oil. The oil filter is very accessable, but you need to take some precautions to avoid oil spill.

High quality synthetic oil will last for many more miles than the Ridigeline intervals, but it also depends on your driving and driving conditions. I have seen cars with service intervals double the recommended for the Ridgeline, and they are using the same oil.

I do recommend the filter to be changed at every oil change. The old filter will contain an amount of old oil to be mixed into the fresh oil, even if you empty it. A new filter is cheap and reliable.
