I've not seen that name come up here, Wendybirdtn, although I don't look at all the rv rental threads. Their website reviews appear to be mostly recent - 2019 most of them. Not saying that's good or bad.
Disney also has pre-approved rv vendors that provide a premium customer experience which are listed on the Fort web site:
Going with a Disney vendor or not is like renting a Disney golf cart versus one from off-site. Non-official providers might save some money and still get the job done but require a little more work/involvement while a Disney solution is easier on you but may cost a little more.
If you end up using this vendor, please come back and let us know how it went.
