The generator most coaches are built around. Representative manufacturer image of the range. Enclosure finish, color and dimensions vary by model and configuration — see the specifications below for this unit. 2,500W LP Vapor 120V · 20.8A 30A CARB compliant Onan is the genset the RV industry standardized on, which has a practical consequence beyond brand preference: parts, filters and service documentation are available everywhere, and any competent RV shop in the country has worked on one. That is worth real money the first time something fails three states from home. At 2,500 watts this unit will run one 13,500 BTU rooftop air conditioner on a soft-start, or the coach without air conditioning. Air conditioning is almost always the deciding load in a coach, and the surge at startup - not the steady draw - is what sets the requirement. Installation into a coach depends on the chassis: whether a generator bay already exists, how the fuel pickup is arranged, and how exhaust is routed.

Installation into a coach is separate and depends entirely on the chassis - whether there is an existing generator bay, how the fuel pickup is arranged, and what the exhaust routing looks like. ### Will the 2.5HGLAA-8310 run my RV air conditioning? At 2,500 watts it will run one 13,500 BTU rooftop air conditioner on a soft-start, or the coach without air conditioning. Rooftop air conditioners draw a large surge on startup, so the practical limit is usually the starting load rather than the running load. A soft-start module on the AC changes that math considerably and is often cheaper than moving up a generator size. ### What fuel does the 2.5HGLAA-8310 use? LP Vapor. LP draws from the coach propane supply, which keeps the gasoline tank reserved for driving and avoids stale-fuel problems during long storage. ### Is the 2.5HGLAA-8310 CARB compliant? Yes, this model is CARB compliant, so it can be sold and registered in California and in states that follow California emissions rules. If you travel or plan to sell the coach out of state, that matters. ## Similar lp vapor gensets ### [Cummins 3.6KYFA-26120](https://utselectricpros.com/rv-generators/onan-3-6kyfa-26120) RV genset · LP Vapor Ships to your door Price $5,026.73 Equipment price.
