There is an old RVnet forum discussing draining the Coachmen FWT. It's for a 31 model so may not apply to the 23 model in which case you may need the 23 manual. It was discussed in 2009. I tried to copy the URL but cannot do so; but you might be able to google it. Also, the 1999 generic Coachmen RV manual is still available online but does not discuss specifically where the drain valve is located. Hopefully someone with the same RV as you can join in here.
That link didn't work for me. Is this what it is supposed to be ?
