There are two main reasons why I wanted to down size. The first is two front end failures while taking a corner. The first was at 25 mpg getting on an interstate in Ohio. LH ball joint just collapsed. I took about a 2 weeks to get it fixed. It was still a harrowing experience for my wife. After it was fixed I assured her it was as good as new. The shop I used back home told me that the shop in Ohio put the wrong ball joints in so they replaced both sides. The following year in Montana while rounding a curve at 60 mpg the rh ball joint failed, dropped, blew the front tire and we almost flipped over. I had all I could do to hold on to the steering wheel and bring it to a stop. To make matters worse the sparks or hot rubber from the front end or hot tire pieces started a fire in the dry grass and came within 20 ft of the MH before some passer by's helped get it under control before the fire dept came. This was in a remote area of Mt. and we could not find a truck stop to work on a Class A MH. Not many truck stops want to work on Class A MHs anyways. The MH had to be towed 250 miles west to Great Falls Mt because that is the only place the insurance co. could find that would take it. The accident happed in July, we did not get the MH fixed until Nov.so we had to drive back in the snow. That really did it for my wife. Turns out the shop back home put in undersized ball joints twice. All P-30 chassis are not the same( another story). So when my wife thinks about all the mountainous windy roads we traveled out west and a front end failure occurred we would defiantly gone over the edge. So the two main reasons is two accidents one almost fatal the second when you need chassis work on a larger MH in a remote area in the summer time when many folks travel finding a truck stop to work on one can be very difficult. I would much prefer a 30-32 ft Class A with a straight front axle but my wife says 3 strikes and your out.
