We do have a number of different lengths of the 3/8" Female Flare x 3/8" Female Flare Swivel propane hose, though I'm not sure if you were asking for 12 foot or 12 inch hose. There is a 12 foot option for this, but not a 12 inch; the shortest length this hose comes in is 2 foot:
- 2 Foot Long: MB Sturgis Propane Hose - 3/8" Female Flare x 3/8" Female Flare Swivel # MBS34FR
- 12 Foot Long: MB Sturgis Propane Hose - 3/8" Female Flare x 3/8" Female Flare Swivel # MBS24FR view full answer...
Weight distribution systems are selected based off of tongue weight which is typically between 10% - 15% of your trailer's total weight. Since you're not hauling water your trailer's tongue weight should be between 300 lbs - 400 lbs depending on what's mounted on your tongue. With as light of a trailer as you have their aren't many options for that low of a tongue weight which is probably what has caused your confusion.
With all of this in mind, I recommend the Equal-i-zer Weight Distribution... view full answer...
