It's much easier to remove the oil line so you can get a box end wrench over the fitting to avoid stripping it off. AMHIK I can change the oil in no time now but the first time had me cussing a few times. If you follow the shop manual you will have a difficult time IMO
There's not a lot of room to work with the hose without using tools (needle nose, whatever) to handle the hose, which risks damaging it. However, I definitely see your point about stripping the bolt and removing the hose allows you to slip a closed wrench over it.
Husky added a sump plug on the 2013 x lite engines, so my schedule is:
I wish there was one on the 2011.
I also wish I could find that stupid hose's part # in the catalog…
