Dad invited my husband to go camping but my husband is saying no

My husband and my dad do not really get along. My dad has never really liked my husband. We started dating when we were 17 and 19 and have been together for almost 20 years. My dad recently said he's taking my brother's camping. My youngest brother is 14 and my dad is doing this camping trip to help "man him up" and having my two other brothers go with him. He called me to invite my husband and I told my husband this could be an opportunity to bond with dad. But my husband is saying that ship sailed 10 years ago and he has no interest in bonding with my father. I really do want them to bond and my dad inviting him could be extending an olive branch but my husband isn't willing to and he said he's not interested in any olive branch. I would love for my dad and husband to finally get along.

Edit: The stuff with my husband and my dad is complicated. I had actually just turned 19 when I met my husband and my husband was 17 almost 18. My dad just never liked me dating any guy. And my husband was no acception. He also caused some issues at the wedding making an extremely offensive speech but that was 16 years ago. He's just always treated my husband badly and this was a very out of the blue things. The camping trip with my brother, my mom explained that my little brother has been really sad because his best friendship fell apart and my dad is annoyed with him moping so he's taking him on a camping trip to man up. My dad is an ass hat. I just feel like our life would be easier if my dad and husband could finally bond. I get why he doesn't want to. Just wish he would since my dad is reaching out that olive branch
