Mines not a toy hauler but it is enclosed and I leave the buggy,raptor and 250r in it along with 55 gallon drums,gas cans and other odor causing items and have never had a problem.
Except for Vp racing fuel U2 and U4 oxygenated fuels.The smell doesnt go away with these.Even if they are sealed tight. The smell comes out the exhaust of the bike. :huh:
