Hi All, I'm thinking Gruv Gear or Rock and Roller. But which model? I'm in two bands: one is 1-2 basses, a pedalboard, amp and 2 speakers. The other is less than that but still 2-3 trips. BUT: my wife just took up drums (and is in one of said bands). Should we be thinking about 2 trips for one cart or 1 trip on a bigger cart? And which one would you recommend? We live in Montreal. It snows here. There are always at least the stairs in our apartment (we live on 2nd floor, car is in basement). Often there are more stairs. BONUS: I occasionally play laptop gigs, so a tabletop could be cool if it's at least 30" off the ground. But this is not essential. Both of us are mid-40s and sometimes throw out our backs. We are willing to spend some money. Thanks.
