Howdy. New to the forum. Appreciate any help identifying a leak I'm seeing under my MH before I haul it in for maintenance. Disclaimer: I'm not a motorhead so very limited ability to service major eng/trans issues. Thanks for understanding :-).2004 Nat'l RV Dolphin, 60000miles, W-22 Workhorse, GM Vortec 8100, Alison 1000 Trans. We've had it 5 years. Used to tow a 2004 CRV, now towing 2014 Jeep Wrangler. Both currently sitting in our driveway. Last trip over Christmas (GA to MS), noticed small leak when we got home.Leak is centerline from a pan just aft of front tires. Fluid is heavier than water but not greasy like oil with no real odor I can smell, small amounts seem to spread out but not evaporate, and I'm not able to tell the color easily.Are we looking at a trans, brake, or landing gear problem maybe?Thanks again. Cheers,Walt

IF YOU DON,T WANT TO HANDLE THE JOB ? CALL A MOBIL TECH FOR RV REPAIRS, MOST ARE FASTER SERVICE THAN A RV DEALER AND WAY CHEAPER, AND MOST LET YOU LEARN AS HE FINDS THE PROBLEM.AND THEY COME TO YOU,

Put a piece of white paper where the drip is. If it is from the transmission it will be red, if from old engine oil it will be brown, if from your hyd levelers, it will be clear. Wipe all surfaces underneath MH that is oily looking. The first pan you see(up front) will be the oil pan, the second one is the transmission pan. The leak could also be coming from one of the lines like a brake line. Once you wipe every thing down it will be obvious we're the leak is coming from.
