I’ve pulled a Demco KarKddy SS for the past 9 years and 50,000 miles in all of the states marked below with no problems. Yes 4 down is a little faster and easier but I love my Vibe and it can’t be pulled 4 down.
Some things to remember:
1. When I first started using the dolly I strapped the toad down as Demco recommended pulling it all the way forward to the front wheel stop then strapped it down but I found that the straps came loose & I even had one strap come all of the way off. I then realized that the straps didn’t slide over the wheel as they are tightened so they remain a little loose behind the wheels and when you started pulling the Toad slip back leaving the straps loose on both sides of the wheel.
I now pull the toad all of the way forward then back up about one inch. I strap it down until the tires squish. As the straps tighten the wheels roll forward and the strap tension equalizes in both the front and rear of the wheel. Since I started doing this I’ve never had a problem with a loose strap. I still check them within 50 miles of start and again each time I stop (about every 2 to 3 hours) but I’ve never found a strap loose enough to cause a problem since.
I talked to Demco about this procedure & they have no problem with it but have chosen not to change the guidelines in their manual.
2. If your dolly is a little wider than the RV watch those right curbs when parking. I ground the lettering off of the right dolly tire before I realized this.
3. Make sure that you allow plenty of front end room when parking along a curb. If you have to turn too sharply when pulling out the rear of the RV swings in the opposite direction pulling the dolly into the curb causing the dolly wheels to scrap or roll over the curb.
