We too have a older Demco with surge brakes and my solution was to buy a third wheel that folds down, that made life easier to move around and finalized my decision not to go 4 down, I normally unload toad then drive little past site then roll dolly either into or along side site then back MH in, worked for us the last 6 yrs, I also found it just as easy to hook up dolly then drive toad on , straps tightened without a problem, we have two different toads so 4 down is not a option " money wise " to us, we are in our early 70's so everyting takes a bit longer but so what-Safe travels my friend -Rich
