We did finance because that is what we do-- finance and they pay off as fast as possible (usually around a year). So we look for no prepayment penalties.
The RV was 59k, sticker.
We put down 3000.
We got 6% loan. (Because we pay everything off early, credit score gets dinged).
We did either 15 or 20 year. Doesn't matter to us because we pay off anyway.
We don't bother with percent of income because we have high income, we will get approved for any amount.
I think we have about 10k left to pay off on the truck we bought within the year (i think Nov 2013) and then it's on to paying off the RV.
We usually like to only do this with one item at a time, but since the RV was on 2014 close out, we decided to pull the trigger since the 2015s were coming out.
