Converting my existing 16\' trailer (7000Lb) to 10,000+..... many questions! Alrighty folks..... here's the simple story: Bought a 7000Lb trailer for cheap when I got my '69 Blazer Tub. It's a 16' wood deck, A-Frame style with dual 3500Lb axles, and NO brakes at all. I want to re-use the upper frame structure and wood deck, and strip out all the springs, hangers, and axles and put in something newer and safer for towing a 5000Lb truck. I was thinking something in the 10,000Lb range would still give me some safety margin (weightwise) without being excessive overkill. Here's where I get a little confused.... I can find places that sell a "kit" to do this exact thing (contains springs, axles, electric brakes, wheels & tires, etc) for example: 10,400Lb Trailer Kit from UtilityTrailer.com The kit is offered at $1099.95 and weighs 800Lbs, so shipping has got to add a few hundred bucks more..... /forums/images/graemlins/dunno.gif I understand "Load Range" on the tires (D vs. E) but what is the relevance of getting a 15" wheel vs. 16" vs. 16.5"??? Is there supposedly something inherently "better" about the larger wheel diameters? I've heard that running "real" trailer tires is the way to go even though they're more expensive. I heard something about passenger tires "squirming" too much when trying to make sharp, slow speed turns....and typically I doubt that most passenger tires could meet the load reqirements for a 10,000 trailer anyway. Does anyone have a source similar to the one above for buying conversion "kits" like what I'm after? Based on the information on that website, is there anything specifically that you'd pay to "upgrade" from what's offered in their standard kit???
