I am very early in my research for a tow vehicle and travel trailer. I plan to sell my home within 2-3 yrs and purchase a travel trailer. I have my heart set on an Air Stream, new, approx 20-22 ft, no bigger. I am a single female and will be traveling alone so I do not need any larger. I also plan to purchase a new tow vehicle. I am leaning towards a Chevy Tahoe but am open to hearing from experienced RV'rs what to look for in a tow vehicle. I have driven a Dodge Ram truck a few times, but it's rather large for me. Your input is greatly appreciated.
