After last week and the fight with that wheel I'd leave whatever it took to be better prepared.
I've decided that:
1. A Torque Multiplier lug nut remover, ( a 1:68 gear ratio can be bought for $60) I bought a 1:78 ratio
2. A 20 ton air /hydraulic jack ($90)....the coach air supply makes using one of these a snap...or it can be pumped up manually.
3. A simple wheel dolly that has a removable handle and and can be stored easily in a bin for $90
are "mandatory emergency equipment" for me.
I could have handled the emergency situation "easily" with the three above items, for a $240 total investment .
Like Carl Mauldin said "I'll never leave home" without those items. I would have paid "much more than that" when I was out there on that hot pavement , soaking wet with sweat and straining every fiber in my body to break those lug nuts loose.
I have a towing policy...but towing an RV with hydraulic brakes problems isn't like towing air brakes, it's a bit more complicated. Especially when they are locked up.
I went ahead bought the big impact for my shop...and didn't splurge on that, just bought one with good reviews from Harbor Freight. It may only get used once or twice..ever. But I'll have it next week when I pull "all" the wheels, service the brakes and change the brake fluid.
