I have been told two different things. One is that you can not have a permanent cover over the gas tank and also I have been told you only have to have access to the fill tank hose, fuel gage connection, etc. What are the regulations and what is preferred?<br />I am replacing the floor in a 17 ft starcraft. The floor origanally had a seperate piece of plywood that was screwed in that was the same size as the gas tank. It was obvious that this is where water leaked through, because the stingers and crossmembers were rotten under these seams. It seams to me it would be better to put in just one peice of flooring. Any comments or suggestions?<br /><br />Thanks in advance.
