The smallest thing we rent Motor home wise is going to be a 24' 0' 22E Chateau class C with the Ford 6.8 V10.
They have plenty of rental units you need to call there or go to the website and see what they have available. They have many different kinds I'm sure one of them would be suitable for what you're looking for at a great price Arlan is one of the best sales reps I ever met.
