Connecting to propane tank on motorhome

Just curious if I can hook 2 10 ft hoses to be able to connect to a tee to run a couple items like lantern and BBQ ? I bought necessary hoses and coupler to add onto my onboard tank, however finally realized the hookup is on the drivers side which is not the side that is usually on the awning side of the motorhome so just wondered if I can add another extension onto it.
