I carry my Echo 330T on trail/camping runs in the truck or SUV, not only to cut trees that are across the trail, but for cutting downed firewood in the evenings, for campfires.
At my grandparents tree farm, both ATVs have milk crates on the racks with the smaller 31cc top handle Echos on them, with fuel/oil/scrench and a set of fiskars pruning shears for anything under 1". Those things get used daily to keep trails open and such, for years, and he hasn't had any problems with them. (Same size as the 341, but 31cc instead of 34cc. Recently replaced by the 27cc model i think)
