i just got mine a week ago and I purchased my r1t in June 2023...it took about 2 weeks to get it after I told them where to send the adapter in an email
my regular carry/cart bag fits easily...i doubt a pro golf bag would fit...i have a bed liner and my golf bag fits in crosswise and doesn't seem to move around, i suspect it would without the bed liner
what made you think the service center should take your add-on stuff off to do the warrenty work...if it was as easy as you say then you should have removed it before taking it in...
