Modesto, Ca to Wilmington, DE in 6 days??

Hello all,

This is my first post. I am going to be helping a friend move from Modesto to Wilmington. We will be traveling in a 17' or 24' box truck towing a car trailer. I am from Delaware. I have never been west of the Mississippi. I was wondering on which route I should take while driving this. It will be in either late December or early January. We do want to make a couple of sight seeing stops but are limited on time. Does anyone have any suggestions for me on the best route???
Thank, J

Easiest route is I-80 all the way across -- then pick up I-76 and I-70 in eastern Ohio and follow that all the way into Philly and to Wilmington. Bob
