Getting back in after a 5 year break

I sold our Class C in 2010 and now 5 years later I have purchased a travel trailer in February. It is just me now and the jury is out about how I feel about the trailer. I have taken one trip (about 1600 miles) and it was very convenient to have everything at my disposal, but I am not as excited to travel now as I use to be. I am 66 and now traveling alone with my dog. I may sell the trailer after I make this next trip through Colorado from Ohio. I am holding off on making a final decision. Part of it is less interest in traveling, and part of it not liking a trailer as much as a Class C. I bought the trailer thinking it is easier to absorb the depreciation than a motorized unit that is not used a lot. I would say that was my major reason for buying the trailer and wanting to drive my F150. If my interest in travel picks up, I could end up buying a Winnebago Trend. It would fit me well, but then again, there is the depreciation piece to look at. I would only buy new, unless I could really find a well taken care of used Trend for a good price.
