Tanalized wood rebuilding of frame

[Markyt1980]

Hi I have read that tanalized wood is not suitable to rebuild caravan frames due to the tantalizing chemicals reacting badly with the aluminium outer shell. If this is the case what wood should I be looking to use?

I don't want it to rot within a year. Is there a way of using tanalized wood but protecting the aluminium shell in anyway?

Many thanks

It needs to be solvent free timber as it will otherwise eat into all your sealents and glues as well.

Some timber decking products now a days are manufacured with solvent free products.
You could also use plain timber and treat it yourself with a solvent free preservative.
