I got the Andersen hitch all setup, it would have only taken 30-40 mins to assemble everything. But my hitch was missing 1 of the big washers that goes between the nut and bushing also I had to put 1 link extension in the chains because the brackets were too close to the propane tank for my taste. Luckily my dad owned an excavating company until he retired 4 years ago, he had everything in his shop that I needed. Everything went together very well, the directions were good also.
I don't know what the actual weight transfer is but here are the measurements that I had. We did weigh the tongue of the trailer the other day with a 1000lb scale we had in the shop, tongue weight was 648lbs.
Also all these were with 1/4" compression of the bushing.
truck empty-- front 40 1/4", rear 40 1/4"
camper hooked no WD-- front 40 3/8", rear 39 1/4"
camper hooked with WD front 40 1/8", rear 40"
Hopefully we will be going camping in about a month, so I will report back with more then.
