coach frank thanks for the reply, i've looked atkustom tanks also they might be the way to go. although i think they are around $450.00 . gotta love those show specials i,m kinda toying with the idea of maybe a fuel cell, but will probly break open the piggy bank and just do it. i,ve tried not to skimp on what i've wanted so far it has taken yrs so far on my 49 and will probly be a couple more before its on the road.thanks again to all for your input.......dave
