Extended warranties are a highly personal decision, based on your financial situation and fear of risk. You don't say if the class A you are looking at is a DP or not. An engine or transmission replacement for a DP can run as high $15,000.
Higher end coach repairs, especially on older models, can add up quickly. How would a $4,000 - $5,000 repair bill affect you? Will your coach end up sitting in the driveway, un-usable, while you continue to make loan payments on it? Will a $1,000 repair bill cause you the same financial difficulty? If yes, then you might consider an EW. It's a matter of how much risk you are willing to take and how comfortable you are with the condition of your coach.
All that being said, these policies, especially for older rigs, are quite expensive. The insurer is in it to make money and they price the policies to ensure that on average, they take in a LOT more money then they pay out. the odds are strongly in their favor that you will not recoup your policy cost in claims. Remember that, no matter how many people chime in and tell you they received way more in claims then their cost of coverage! Regardless of what they say, they are in the vast minority!
When we bought our first DP, we had no experience with them. It was a 2003 Monaco Executive, bought in 2010 with 62,000mi on it. As we were going into such an unknown, we did buy a 2 year EW. Over that two year period, the only thing we had replaced was the alternator, so we didn't come close to recouping our cost. BUT, we felt a lot more comfortable while we were learning exactly what we had for a rig. After the two years, we did not renew the EW. we had the rig for 2 more years with no issues.
Sorry for the long winded post, but this topic comes up often and so many people think it can be answered with a simple statement that the EW is either a wonderful or a terrible idea. It can be either, depending on the situation. One thing for sure however...... If you do decide to buy one, take lots of time to read the policy, understand the fine print on the coverage and ask questions. THIS IS CRITICAL!
