Mighty's current US deal is 15% off Mighty Class C rentals, booked by August 31, 2026 with drop-off by October 31, 2026. There's no code to type: it applies from the deal page. Mighty's US bookings run on El Monte RV's platform, so El Monte's typed LONG10, LONG15 and LONG20 codes cover Mighty vehicles too, at 10% to 20% off longer rentals with 50 free miles per night.
Mighty is a thl brand renting campervans and Class A and C motorhomes in the United States from seven pickup points: San Francisco, Las Vegas, Los Angeles, Orlando, Denver, Seattle, and Linden, New Jersey. Its vehicles are pet-friendly and carry air conditioning and generators.
The 15% Mighty special
The discount applies to vehicle charges on Mighty Class C Medium and Large motorhomes with no minimum rental period, which is unusual: most fleet deals want a week. Blackout dates are May 13 to 19, 2026 and August 22 to September 11, 2026, it's valid for US license holders on new bookings only, and it doesn't combine with other offers.
The codes that cover Mighty vehicles
El Monte's LONG codes and its AAA member discount both extend to Mighty vehicles, since the bookings run on the same system. Thresholds, dates and the AAA paperwork are on our El Monte RV page.
Australia and New Zealand
Mighty also rents across Australia and New Zealand, and those deals surface through the booking filter on mightycampers.com's deals pages rather than as posted codes. Pick your month and pickup city there to see what's current.
If you're weighing a campervan against a small motorhome for the trip, the difference between Class A, B, and C motorhomes is the five-minute version. And before you book, check your dates across the market on our campervan rental listings.
