I would dearly like to know how fast the Tq on the Pudge will push your AT34, since that's what I want to push. Please do that experiment and report back!!
Not sure of the specifics, but I think you can discharge the in-use battery on the Tq much faster than you can recharge the spare from the genset, with typical equipment anyway. So you'd go a little, then rest a little. Which is better than not going. Wires (and suitable converters) from the genset to the Tq would allow continuous use.
