ReadyBrake from AdventureRV--comes in two versions : Integral to a tow bar, or (if you already have a tow bar) they have an add-0n to the receiver. Simple to use, good pricing.
Just bought my first RV, a 1999 Newmar Mountain Aire and can not get into the spare tire well.
I do not see any latches or levers. Please send any info on this problem.
