I have been following this forum with great interest and have decided to give the Andersen Hitch a try. Never had to use a weight distributing hitch with our Chalet folding trailer. We purchased a 2012 Lance 1575 TT in late 2011, and it will be towed by a 2006 Honda Pilot 4WD. The Lance has a GVWR of 3500 pounds, which coincides with the Honda's tow limit of 4500 for boats and 3500 for all other trailers.
So far we have had two 80 mile trips with the Lance. The first was without any suspension enhancement, and the Honda really sagged in the rear. Then had Timbrens installed, and there was considerably less sag and improved handling on the second trip. Still thought it sagged a little too much, and also would like the assurance of sway control even though there haven't been any sway issues with the Lance. So, decided on the Andersen.
The hitch is installed and have utlized the local CAT scale, measuring and weighing various configurations. The data is contained on the attached spreadsheet. Don't know how to attach a spreadsheet, so I scanned it and attached it as a photo.
I adjusted the spring tension until the front fender was within 1/8", which amounted to 1/4" of spring compression. I am a newbie at this weight distribution stuff, but I am thinking that there may be a little too much weight distributed to the front axle and trailer axle. Would appreciate your input on this.
You will notice a 20 lb. discrepancy in the figures. Nothing changed in either the TV or TT that would cause that. I am surmising that the CAT scale weighs in 20 lb. increments and that maybe the rig was right on the bubble.
Am comtemplating another visit to the CAT scale where I measure and weigh each 1/16 increment of spring compression, up to 1/4 inch. This should give me the info need to "fine tune" the setup.
