My class A 40ft DP will be 20 years old this year. In all that time and over 100,000mi it has been in a camp ground twice. I use it to tow my race car to the track and to stay in when races last several days. Have spent a lot of nights in truck stops and rest areas mainly because I am 72ft long and you know how that works out in a camp ground. I also keep it at home and powered up at all times. Been thinking about getting a newer one but hard to get this quality that I am used to in a newer one......Use them, they love it.
