I am curious of what 5th wheel means. And so I asked one of my friends in which she answered that if I have RVs or travel trailer then that will be the time that I will have 5th wheel. I asked her why she knew all of these and she said that she has 5th wheels with of course 5th wheel warranty just in case she needs some 5th wheel service assistance someday. Also, she added that she’s enjoying her 5th wheel vehicles since these are so handy whenever she will have to travel anywhere she wants with her families and friends.
