I've got one for you guys. I live in Florida where it gets hot and I keep my TT in a storage lot. The ground is asphalt which can get over a 100 degrees. Does parking the TT on wood help prevent dry rott? I noticed recently in a condo near by that the snow birds park their cars on wood. What tips do you guys have?
Will take a long time to see any dry rot, but two things if you are worried...
put a "nonconductive" surface like plastic sheeting or something on top the wood
and cover the wheels with tire covers to keep the sun off them ...
or just do like me --- about 5 years is all the 'safe' life you can get out of an st tire and that is way before any 'old age' sets in good luck !
