Unfortunately they will likely send the same guy or someone from the same shop with similar limited knowledge. I am not usually a fan of referring to a retailer(working in CS, 3rd party retailers were our sworn enemies), but this is definitely one I would be comfortable saying would be their forte. Plus, I have seen a lot of the retailers on here and I would trust these more advanced setups outside the norm to them as they like money. Incentive to not only learn creative ways, but creative ways to do it right and efficiently. Otherwise they get charge backs. What's your zip code, might be able to locate some numbers for you via Google. The RV guys are the best(judgement call).
