Finally got our motorhome out of the Camping World service center a few days ago, so I was able to set up the tow arms and cables to see if they would fit the Gladiator. Motorhome has been in the shop since May (one of the worst customer service experiences ever) and I got the Gladiator in early July and had the tow plate hardware and connections installed by the dealer. After the first test fit, I found that I needed a different hitch extension because the arms were too far from level. Amazon delivered the new extender (2" drop/rise) today and it looks like it will work. Took it around the block to test the brake adjustment and it seems to work well. Nice that there is no steering wheel lock!
