Thanks everyone for your incredible input. Yes, we have the smaller Legacy Elite, (Hull #799), which doesn't have the contortionist tool, er...access port. Being that we want to be able to use a filter when filling the tank, space is a big issue for us and most importantly, I'm just a lazy bum, we're going to give the drill pump method a try.
PS: I would have responded with my thanks earlier, but we've been too busy enjoying life on and off the road!
