Best way to ship a shell and rear end across country?

Cheapest way is to go and get it. Dont be skeered of snow and ice, you will need to go slower w a trailer. When driving on this stuff you have to feather the gas, and brake, and go easy on the steering, not get really jerky with the wheel. Leave a lot more room between you and the person in front of you especially with the extra heft of a trailer. Ex. If you start sliding sideways, slowly ease off gas, and let off the brake, steer into it. If sliding to the right, turn left etc. Do not EVER use cruise control. Most major highways up there are cleared well. Its secondary roads that suck. Once your on a major highway its smooth sailing because they clear those very quickly after a snow storm.
