Got this number for Sallie Mae from my wife.... 856-642-8200. Hope it helps because I can't find out squat online about their RV financing either.
Was pretty quick actually. Bear in mind we both have had student loans with them in good standing, even through my bankruptcy (and my wifes when she had one a few years before we were married) and this is also our 2nd RV loan through them.
Filled out ap in the late afternoon & had reply by noon the next day.
My pay is in 2 chunks, I get a 50% advance on the load and then get the remaining 50% settlement when I turn in the paperwork to the company.
One benefit I have is I am a contractor that is permanently leased to a company so I can list an "employer" besides myself when I have too.
My only proof until I get a 1099 at the end of the year is an email each time from Comdata showing the advance or settlement amount that is loaded onto my comdata card.
They wanted to see 1 month (last months) worth of statements(emails) showing I grossed what I said I did.
That almost bit me in the behind when I stated 100k annual gross for the business + my VA disability as the last few months have been slow and I've taken several weeks off to go camping, goof off etc while it's slow.
Barely pulled that one off having to come up with $8400 in email statements + the bank statement showing my VA funds direct deposited into my account in the last 30 days....... and a few of those emails were accidently deleted OOPS

but I did pull it off.
Guess I should confess my sins and say I did this last month when I bought my '07 Fleetwood Wilderness 295TSRL fifth wheel and traded my '06 Fleetwood Wilderness 270 FQS travel trailer.....
Sorry Jim.... Had nothing to do with brand and everything to do with the dealer who's just a few miles from my house vs 100 miles for any Heartland dealer (hopefully this will be remedied someday).
I know the owner and have had great service from them. I deal always deal directly with the owner there and when he asked me if I wanted to buy it when I had mine there for service I told him he better make me an offer I couldn't refuse.... He did

. Now if I can only get him to carry Heartland products too.
