About this RV
A Class C diesel with a front living / rear bedroom layout, three power slide-outs, and a well-documented list of ride and roof upgrades. This 2020 Jayco Seneca 37TS pairs a front living / rear bedroom layout with a well-maintained history and a meaningful list of owner-added upgrades. A Cummins diesel powerplant, triple slide-outs, dual ducted air conditioning, and an enclosed underbelly make it a turn-key choice for full-time or seasonal travel. Ride-quality upgrades — Sumo Springs, Gabriel shocks, and a steering stabilizer — combine with a lifetime-warrantied AeroArmor roof system for genuine peace of mind on the road. The DOT date code on this unit reads 2524 , meaning the current tires were manufactured in the 25th week of 2024 (approximately June 2024) — consistent with owner records showing new Toyo tires installed in August 2025. As a general industry guideline, RV tires are typically recommended for replacement every 5–7 years regardless of tread wear, due to age-related rubber degradation. At roughly two years of age, these tires fall well within that window. This unit does not include a spare tire.
