Broken lug bolts
Felt a slight wobble while driving north on I-75 in GA. quickly pulled to side e found left rear street side she'll still in wheel well, but all bolts sheared off at hub. Tire and 16" Sendel wheel look ok. Any ideals in hot what caused this. Limped to repair place and srrayed in hotel last night. Thanks in advance.

Guess: Either torqued too tight or you hit something with that wheel. Could also be faulty wheel, we had it with a number of golf carts years ago where I worked. Hubs were defective and lugs pulled off.

broken lug nuts.
Found another thread on the forum with the identical problem on another 2004 Classic. Probably just a coincidence. Looks like it may be a torque problem, but I checked torque last week and had 120# on all wheels. Only about 700 miles since then. Is this the right torque, and should I check more often?? Thanks for the replies.

I'd be curious as to when the last time was that the wheels were put back on the trailer.... what was used to tighten the lug bolts, how tight?
I have a real disdain for air tools being used to tighten lug bolts. I use an manual adjustable torque wrench, and if someone else is doing any tire/wheel work for me, I ask them to use the same. Knowing the proper torque is a great first step.

Lug Torque
Pat - Not sure about 2004, but our 2006 30' Bunkhouse with the aluminum wheels was originally listed at 110 lb/ft of torque in the manual. That was changed by the factory to 100 lb/ft after production. 120# sounds a bit heavy.

Broken lug bolts
Most ALWAYS, broken lug bolts/studs are a result of driving on loose lug nut bolts or wheels that don't fit right or are not seated on the hub properly.

My 04 classic said 80 ft lbs, my 13 classic says 110 , 120 might be a bit too much, I would certainty look over the rest of them......

After reading all the posts, I might add when I rotate the wheels,I torque at 110, and retorque every 25-50 miles until they are seated, makes you wonder when the above were re- checked, like mr Morgan says maybe were loose....what about the rest of them?...

My 2015 'Cloud calls for 110 ft.lbs.
So does my 2016 30' cloud.

TRUE!
Undertorquing will result in ' fatigue' breaks, and overtorquing will result in stretched bolts; ergo: " CRACK!"
Use a calibrated torque wrench, and follow the Mfr's spec.
THEN if it breaks, the Mfr. is ' the goat', not you.

Lug nut torque: Here is a chart posted by E-trailer, note some of the values change with aluminum rims.

Torque for aluminum wheels with 1/2" studs per Airstream is 110 foot pounds. This has been the torque for at least the last 8 model years. Wheel diameter does not play a role.

Tires with too stiff a sidewall will also cause the bolts to shear off especially if you make a sharp turn.

J Morgan,
Interesting citation and it reinforces using a torque wrench or torque stick with air tools to achieve the correct clamping force of the wheel to hub.
But the current thread about torque wrenches, your own comments basically summarized as, not required, in many variations.
I use a torque wrench on all wheels that I work on.

Broken lug bolts
I don't have to agree with EVERYTHING in a post for it to be otherwise informative. 
I have no issue with anyone who wants to use a torque wrench to tighten lug nuts, but I don't,,,, and pretty much wont..
