Hello all, Am completely new to the world of RVing and would like as much or as little advice that you good folk could provide. Will be based out of the Vegas area and will be looking to do 1-2 week trips 2-3 times a year mainly to the National Parks around the States. We comprise the Boss, the 3-4 year old daughter, a 2 year old and myself. Am completely open minded about the most efficient way to travel around. Should I buy a travel trailer with a decent size towing vehicle?? Should I buy a C-Class?? Should I buy an A-Class bearing in mind the fact that the majority of trips will only be that 1-2 week time frame?? Is a 30+ footer going to be a pain in the backside heading up through the mountains ie Is it going to be too large to take certain roads?? What are the relative comparisons re petrol consumption between the different classes?? As I am not looking to do this full time I would only buy second hand with the possibility (high likelihood) of upgrading in the future. If I was going to do it for a year or 2 then I would probably have a different mindset. Any assistance that you could provide is greatly appreciated.....trust me!!
