My FI and I are getting married in a historic church.  It's not used as a church anymore, so no priest, organist, etc. and we have to supply our own music and sound system.  No biggie, FI plays guitar and sings at bars and has all his own equipment.  The caretaker will come to unlock the doors for us, then leaves and comes back when we're gone to lock up.  We live 3-6 hours away from all of our family members and (most of) the wedding party, and we are providing a trolley to transport our immediate families, bridal party members and their OOT SO's from the hotel to the church and back.  My FI and I were thinking of asking 2 of the husbands of my BM's to break down the sound equipment and put it in the trolley while the rest of us are getting pictures done.  It's going to be 2 speakers and stands, the main sound board and wiring.  Not heavy or a lot of stuff, but it needs done.  These 2 guys are the husbands of my best friend and my cousin, and I've known them each for about 10 years.  They will be hanging out with the groomsmen all day before the wedding and are getting GM gifts.  (FI is buying his guys cigar cases and cigars.  All of them do smoke cigars, occasionally.)  
All that being said, is it rude to ask them to break down the equipment?  In my head, I feel like they'll have nothing else to do while we're getting pictures done and it'll take about 8 minutes to do it and they probably won't mind.  At the same time, if it's only going to take a hot second, then should FI just do it himself?  But, we're getting married at 5:30, done at 6, and want to have pictures taken outside, so we risk losing some daylight while breaking down the speakers.
4 months out and this is what I'm stressing out about.
