This is the first website review I have ever written. I can personally attest to all of the great reports I have read regarding your company. I must say that 12Volt-Travel definitely deserves leadership positioning in the RV field. All of my emails were responded to in a very timely and professional manner. My telephone conversations with you were both first class. I received tracking on my order in just under two days and delivery the next. Some other websites I've dealt with charge extra to guarantee your order will ship within 2-3 days. Your company stands head and shoulders above the rest. I will be sure to mention your name amongst the groups and gatherings that I attend. K. Sampson — , MO, USA —
