The R&M Jack Back OnTop relocates the trailer jack back to a stationary steel platform shackled to the tongue. Allows full tailgate or rear door opening, unlimited rear access when hitched, and ends tailgate-hits-jack dents. An electric or manual jack can face any one of a dozen angles, one every 30º, so the up/down switch is always handy. All 2" wide trailer frames of all heights are supported. OnTop is available in three models:
▶︎ OnTop, $199, includes (1) 16" and (1) 20" mounting bars. Moves the jack back 8 to 12 inches from stock.
▶︎ OnTop Plus, $229, includes (1) 20" and (1) 24" mounting bars. Moves the jack back 8 to 17 inches.
▶︎ OnTop Maxi, $279, includes (1) 16" and (1) 20" mounting bars, adds (4) 16" extension bars, and moves the jack back 38 inches, as far as is possible for most trailers. The Maxi can mount two batteries, one on each end.
▶︎ With optional Side Arms, all three models can attach two propane tanks, tool box, storage container or other accessory.
▶︎ Our rust prevention technology, Hot Dip Galvanization, is fundamentally different and far more durable than all others! Molten zinc actually penetrates the steel and metallurgically combines with it, and cannot be compromised by chipping, peeling or scratching. If damaged, zinc oxidation builds a new protective layer that maintains protection. Looks good on day one and remains so indefinitely.
▶︎ Temperature Range: Between -40ºF and +392ºF.
▶︎ Expected Life Span: Near saltwater, decades, inland, over half a century!
▶︎ Optional Propane Lock discourages grab-and-go theft.
▶︎ Optional Side Arms attach a standard Double Propane Tank Rack, storage, tool box, etc. 5 gallon 20# and 7½ gallon 30# tanks supported.
▶︎ R&M recommends two excellent products that deliver unique benefits to many trailer owners and merit your serious consideration. R&M derives no profit from their sales, but long experience makes us appreciate their value.

Jack Back OnTop
• All OnTops move the jack straight back, still in the middle, irrelevant for most trailers, but RV and livestock trailers , with people or animals moving about inside, may be more comfortable with the perfect balance of a center-mounted OnTop or Side-to-Side.
• Or put an OnSide on each front corner to minimize side-to-side motion inside and maximize overall stability.
