Motor Home Age and ESP?

I am seriously looking at the ESP on my 1998 Four Winds Motorhome. However, I see that is has a 15 year old vehicle limit. I am within that limit at this time, however, if I got it this year, would it expire next year as it turns 16 years old? I don't want to buy and have it cancelled after only one year of the service plan. Otherwise, I am really looking at buying the plan.
