Financing for your RV
Classy RV has partnered with our friends at SeaDream Finance to get you the best financing available. They work with 22 lenders to bring you the right financing options for your RV.
Click the link below to apply. Just "kicking tires" at this point, no problem. Get preapproved now so you can act quickly when you find what you want. Preapproval speeds up the loan process and gives you leverage with sellers.
Once you've narrowed down your RV search, we recommend considering a 3rd party inspection of the unit. This will allow you to set eyes on the vehicle and determine it's mechanical condition, without ever having to leave home.
We recommend Premier RV Inspections. They work with qualified inspectors nationwide who will come out to the rig's location, review the condition, and send over a full report--including photos!
An RV warranty, like those offered by Wholesale Warranties, will step in to pay for these costly repairs. From your engine and transmission down to your leveling jacks, slide-outs, and appliances, these policies will take care of the repair bill, and get you back on the road where you belong!
