This is a contentious topic for sure. I emailed Keystone and asked, “For my Zinger 211RD where are the proper jack and jack stand points to raise one side of the trailer for service,” and they replied, “Thank you for your inquiry. You can do all 4 corners or at the rear about a foot behind the rear axle. We do recommend contacting your local Keystone dealer for assistance on repair(s) and or part(s) needed. If you need assistance locating a local dealership, you may utilize our online dealership locator: www.keystonerv.com

I, like most of you have heard, “don’t jack from the axel,” and “corners are for stabilizing only, not lifting off the ground.” But then they tell me this. Here’s a secret I will admit, don’t tell anyone, one time when leaving camp, I let the tongue jack down having forgot to retract the front corner stabilizers putting all the weight of the front of the trailer on the stabilizer jacks. Nothing exploded.
I also heard all about the “China Bombs,” and I don’t doubt that there are plenty of crappy tires out there, but the ones on my Zinger dual axel have lasted about 5000 miles now, have worn evenly, and still have plenty of miles in them. This trailer came standard with 70mph speed rated tires. I’m going to keep driving them until they wear out of we have our first tire failure, THEN we will replace all four keeping the current unused spare as the spare.
I hope this information is useful to someone.
