This is supposed to be a discussion forum about lawn and garden tractors. Discussing is what we do here so you should expect that your post might be discussed.
You came here in the hopes of finding a buyer for this trailer you built. That makes your post an ad.
If anything, my posts have raised the profile of your post on this site so if you were looking for interest, you certainly found some. Whether any of it will result in the sale..... wait and see.
