<human>: My wife and I are currently nomads and she has been taking travelling RN positions for the past 6 months or so. She works and I stay home with our son. Currently we pay roughly $12-1300 per month to stay in furnished homes. We want to buy an 5th wheel RV to take with us to cut the cost down for housing. 

We both have good credit history but since we have pretty high credit card utilization we aren't sure which path to take.

She's got a job in Indianapolis lined up that would allow us to save enough money to pay our credit cards down to less than 20% utilization in 13 weeks about $12,000.

So my question is: would it be better to save our money and then use that plus our savings to pay down CC's and restore our credit scores to then find some financing for the roughly $17,000 we want to spend on an RV or is it best to hold our CC debt and pay it with the after we outright buy the RV? 

We'd have no rent payments at this point besides the roughly $5-600 renting a camp ground would cost. Our thoughts are then that the $600 could go towards doubling the minimum payments or tackling one card at a time based on interest rates. Each has roughly $7000. 

We would have near zero other debts besides our $300 car payment at that point and don't really plan on seeking other credit for a while.

Summarize the given text in a few sentences.
<bot>: Save money and pay down CC's in three months to get financing for RV and cut rent in half or buy RV, cut rent in half and then tackle CC's?"
