To buy or not to buy is a highly personal decision. I always ask one question:
If you have a major failure, will you be able to cover the cost of the repair, or will your rig be un-usable while you continue to pay on your RV loan?
In a FW, a refrigerator replacement is a $1500-$2000 job. That's probably one of the biggest single item repairs you could face. Of course, other multiple problems could add up to more than that. With a new rig, the chances of you recouping the cost of the policy in claims is very slim.
EW companies are VERY profitable. That only happens because they pay out far less in claims than they take in in policy sales.
When we had our DP, I had no prior experience with them and the thought of a $15,000 engine or tranny replacement was daunting, so we bought into a 2 year EW. After learning more about the coach and becoming more comfortable with it, we did not renew.
Now, we just traded for a Cyclone TH (new) and have no plans to get an EW. but that's just us..... You have to decide for yourself. Eyes open and educate yourself on these policies. READ & UNDERSTAND THE FINE PRINT!
