OK.. that is the origial chinese goat roping...
it actaully goes OVER and then UNDER different things like the brake rod and
like that. the way I do it...and I know I don';t do it the right way <ahem>
is to installthe hose in the body and lit the tank into position.
then you SNAKE your hand on the badk ot he wheel well and over the frame rail
and fumble/press the  plastic "tee" fiting into the tank grommets (silicone
spray)
it takes a tiny hand (I'll bet thin women did this at the factory) adn the
camper with A/C is the pits but it can be done..you WILL hurt your hands if
you're a big mitted chap or dame....
if all else fails I'll be in GA next week and maybe I can help ya out...
