I agree with the above statements....but sometimes its nice to have something extra on a new RV. They will start out at like $3000 or more for this stuff.
Tell them NO, then stand up. Then they will say $2000, do the same. Then tell them $500. I got mine for like $800 or $900 for 5 years but It don't sound as good as yours.
Looking back I wish I never purchased it but I was new to RV's and was scared not to.
You can alway get an aftermarket one if your just feel that you have to have one.
If your handy at all DONT DO IT. Most of the stuff I fixed myself super cheap.
