Hi everyone I'm new to this forum and hope to learn some great things hear. I'm going on a trip from Nashville,TN to Denver, Colorado then to Lake Tahoe and then finally to Portland Oregon just wondering what was the safest and with the least elevation possible. I'm new at RVing and my rig is a 2003 Dodge Ram 2500 turbo diesel 2wd quad cab long bed. The RV is a 31' fifth wheel camper. Any suggestions would be much appreciated thanks.
