Welcome LV,
Welcome to MySwag.
Certainly a worthwhile change if t isn't too much more.
Not only good to have a second spare, but it can be a pain to get at one of the spares, if you have two avaialble then you have options.
Having said that we did that when we ordered our camper, then prompty upgraded the tow rig so it doesn't match anymore. To retrofit will be very expensive so doing it first up is a good option if avaialble.
