I always get my own luggage and bring it with me on DME. We arrive after check-in time so we like to unpack before we get going. We're two adults so we just have one bag each. I'd also like to point out that even the people who don't get their checked bags and bring them with them, I'd say a good 80% of people have larger carry on bags that they ask to store under the bus. Last time we took DME, the line of people waiting to get on was stalled because everyone had at least one bag - whether suitcase or carry on duffel - they wanted under the bus. It's a fact of DME. Relating to OP, on your next trip, I wouldn't worry about others complaining if you opt to bring your own bags on. We've never had an issue and the driver won't either if you tip appropriately.
