I picked up my 5er last week and already had an issue, I called the dealer who couldn't help for a few weeks but then a shot in the dark, I called Forest River, subsequently they got me to the service manager (awesome guy) who had me bring my 5er in the next morning (I was traveling through Indiana anyway) and fixed everything but that's for another post.
My point is, I asked their service guys at THEIR facility and his words regarding whether or not the second service year is worth it was ........."You'd be utterly stupid not to get it as it extends the same coverages as your original one year warranty for a small price"
As what I had repaired on my 4 day old trailer if it were out of warranty between fridge, microwave, Television and converter would run me about 3 grand in parts alone without even getting into the labor.
I haven't got mine yet but plan on it VERY soon
P.S. If you are in or near Indiana, and you have issues that would be covered by warranty, I would highly suggest if you cant find any help, call the Forest River number on the back of your owners manual, they will connect you to the warranty advisor for your unit. In my instance he called me back after I told him the issues within 5 minutes with the FR service manager in the room who talked me through some trouble shooting and then decided since I was headed through his area to bring me in first thing in the morning. This is the place the dealers send the rigs they don't know how to fix or didn't fix right. Never hurts to try but they accommodated me with time and had all the parts and appliances needed on hand for a total of about 4 hours from start to finish
