I currently live just south of Memphis. The two main companies I've seen discussed for rental RV sales are Cruise America and El Monte. There is a Cruise America company just north of Memphis for rentals (not sales) and that's where I'm looking to rent from. However, I think I'd like to buy from El Monte because the conversations I've seen about rental RV sales indicate they are more forthcoming with their maintenance records and the Cruise America staff can at times be rude and inconsiderate.
I should add to my previous post that I am currently debt free except for a house note and will not be going into debt for this purchase. There is a possibility that when I am done with the vehicle I will give it away. My current steady income stands at $500 per month once I quit my job so the fewer expenses I have when I hit the road full time the better.
