There are no custom-fit hitches for your 2000 Prevost H345, so the only thing you may be able to do is use a universal, weld-on hitch, such as the Curt Class 5 Universal Weld-on Hitch w/ Brackets - 2-1/2" Receiver - 62" Wide # C97CR.
This will work with frames that are between 18 inches and 62 inches wide, and has a 20,000 lb capacity. I have added a link below to our entire list of weld-on hitch options.
Then for a 24 volt brake controller you'll need the Redarc Tow-Pro Elite Brake Controller... view full answer...
