The answers on the Essex Credit web site were excellent.
Since you have an excellent credit score, you may have a significant equity in your home and you can use that as collateral for a loan. Using your home allows you to consider a older (over 10 years old) diesel motorhome that those with poorer credit could not qualify to buy, thus reducing the potential market and the price.
Also, since you can qualify for your own financing, you can consider buying from a private party. Buying an older high quality diesel pusher from a private party is what we did (although it was 10 years ago) and we couldn't be happier.
