Three El Monte RV promo codes are live as of August 2026, and they reward trip length. LONG10, LONG15 and LONG20 take 10%, 15% and 20% off the nightly rate on rentals of 10, 15 and 20 nights, each with 50 free miles per night included. Book by December 31, 2026 for travel through April 1, 2027.
El Monte RV owns and operates its fleet out of rental centers across the United States, from Los Angeles and San Francisco to Chicago, Orlando and New York, and it discounts the way fleet operators do: typed codes for some deals, automatic seasonal discounts for others. If you're deciding between its motorhome sizes first, start with the difference between Class A, B, and C motorhomes.
The codes you type
The LONG codes are the only ones to enter at booking. The mileage half of the offer compounds them: El Monte charges mileage separately from the nightly rate, so 50 free miles per night on a 15-night rental is 750 miles that never reach the invoice, on top of 15% off the nights.
The codes cover El Monte's Class C fleet and the Mighty Class A, B and C vehicles that share its booking system. Our Mighty page covers those deals separately.
The deals that apply without a code
Each of these applies automatically on eligible dates from its own deals page. As of August 2026:
- Summer Special. 10% off the nightly rate on Class C motorhomes. Book by August 31, 2026, finish travel by October 31, 2026. US and Canadian licenses only.
- Winter Special. 20% off the nightly rate and 100-mile packages on all vehicles for travel November 1, 2026 to March 25, 2027. Book by August 31, 2026.
- Early Bird Special. 10% off 2027-season rentals, travel April 2027 through March 2028, minimum 4 nights. Book by October 31, 2026.
- Pay in Full Discount. 2.5% off the total booking when you pay upfront rather than leaving a balance for pickup. Book by December 31, 2026.
The AAA discount
AAA members get 10% off the nightly rate, 50 free miles per day, and half off the vehicle readiness fee. It isn't a typed code: create a quote, then send your membership number to El Monte's reservations team and they apply the adjustment. US residents only.
Fine print that matters
The discounts apply to vehicle charges only, so kits, generator hours and taxes price at the standard rate. One offer per booking: the seasonal specials don't combine with each other or with the LONG codes. New bookings only, and each deal carries its own blackout dates, listed on its detail page.
Before you book, check the same dates across the rest of the market, starting from our RV rental listings.
