That's up from last year's total of 208.
Organiser Alan Weeks attributed the high numbers to a stellar line-up and similar events around the region that drew music and RV lovers to the area.
But he says he was disappointed with the local support, which was lacking in both volunteer ranks and patron numbers.
“Apart from the festival committee, we only had one person from Kyabram actually come and volunteer,” Mr Weeks said.
“Luckily some people came forward to help us on the gate, otherwise we might have been overwhelmed.
“But that was people who had paid to see the acts and who instead were volunteering their time, which just isn't fair.”
Last year the festival garnered stunning financial returns for the region, according to a Campaspe Shire report.It found the November event contributed an estimated $69,290 to the local economy, which translated to an average spend of $364 per RV vehicle.
An additional $16,654 was spent in Kyabram alone on the hire of equipment, accommodation, food and fuel by the event committee.
Mr Weeks said he would like to see businesses donate an hour or two of their time to run the festival.
“Even just a couple of hours on the gate would help us immensely next year,” he said.
Among a star-studded line-up of acts, a special guest was also present on the Friday and Saturday night this year — newly elected chairman of the Campervan and Motorhome Club of Australia, Kim Atkinson.
“It was a real coup for Kyabram to have her there and just goes to show what an event this has become,” Mr Weeks said.
“We'd love for more people to get involved."
