Should I switch to synthetics for a long trip south?

I use Rotella 15w-40 year round. I will traveling to Florida next week for 2 weeks and I will be pulling a 34' travel trailer. Would there be any huge advantage to changing to synthetic oil for just this trip? Like say Rotella 5w-40 for example? Or should I just stay with what has been working? I am wondering if the heat down south would be a good reason to change to the synthetic?

As far as heat is concerned down south a 40weight either from a 5 or 15 is still a 40weight oil, plus if he is going to be towing a 34' trailer syn is definately better at protecting the engine because syn can protect far better from break down due to heat.

I would be more concerned about the tranny fluid towing something that big. If not already running syn in the tranny seriously consided switching
