I'm trying to decide on a travel trailer to live in for a few months until I can get settled in another town. No one wants to rent an apartment for a few months, so this will be the next best thing. I'm searching for a used one, but there are so many and I have no experience with travel trailers. I understand fiberglass will be easier to haul, heat and cool, but I have found an aluminum one I dearly love. Can anyone enlighten me on these. I will be using it in very cold weather for awhile so I can use all the advice I can get! Is there any such thing as an "insulation rating" given to trailers or are they all the same? I plan to sell this trailer in about a year, so I want to buy one that is going to sell fairly easily. As you see I have many questions.
