Hoblick Posted January 14, 2013 Report Share Posted January 14, 2013 so a few ago i purchased the Harbor Freight 4x8 Heavy Duty 1700lb capacity NON foldable trailer to build as a track bike hauler to haul with my sonata.the gas prices killed me last year lugging the enclosed trailer behind the Titan. I have an upcoming trip to Jennings GP in march and needed to haul 2 bikes.so the idea behind this is to be able to haul 1 or 2 bikes on it.i went back and forth about buying a used trailer on craigslist, and just kept seeing junk tailers for way to much money. read some really good reviews on the non heavy duty foldable trailers all over the internet, but didnt want a foldable deal. just figured it would be a weak point in the tailer.so saw the 1700lb capacity HD non foldable and thought that would work well for me. the other plus is it has the 6 ply tires with 1095lb capacity per tire. downside is they are 12" wheels, but we will see how she does on the interstate and if need be ill upgrade.so day one was just spreading the parts out and seeing whats what. got the frame bolted together and then went to work.i knew from the beginning i was going to weld the trailer here and there to give it more strength. mainly the seam between the 2 halves.after a bit of scuffing and some rustoleum red paint protect where i had welded, i got the suspension and axel together and mounted. I pulled the bearings out inspected and then regreased with some high quality synthetic bearing grease and reinstalled.i kept going back and forth and back and forth about what kind of deck, thickness, and how i was going to secure it to the frame. ultimately i ended up going with 3/4" pressure treated plywood and carriage bolts. I really wanted to do an aluminum diamond plate top on top of the plywood, but i wanted to get the deck on and aborted that idea for the moment. i may or may not do that in the future.I still had my wheel chocks from my enclosed trailer, so i measured out where they needed to be and mounted them up. Got the lights mounted and all wired up as well. still need to solder the connections up and heat shrink them.i also got some angle iron and made 2 extensions in the front of the trailer to run tie down points to. i was going to weld them on, but figured if i ever needed them off id be screwed. so there were existing holes in the trailer frame, so i drilled holes in my angle iron, painted it up with some red rustoleum and mounted them up. also got the spare tire mount mounted.then it was time for a test fitment and make sure the lights worked.after that was done i realized i need a bit higher raise on my ball mount. the trailer is angled down in the front a little to much, so ill be shopping for something with a bit more raise. just gotta measure to find out what i need.finally i figured id better go ahead and get the fenders mounted up. dont do this last like i did, its a pain in the ass.thats where im at now. still need to mount some tie down points for the front center and all the rear points. need to make a mount for my ramp underneath the trailer, and contemplating my next steps. Im either thinking of putting a large plastic waterproof storage box up on the tounge area, or weld in some steel, cover some of it with 3/4 ply, and frame out a vnose area with some steel and diamond plate aluminum to make it a bit more aerodynamic and would also double as a rock guard, as well i could store my gas can and some other things behind it.then i also have the idea of mounting the base of my tire changer there, or in front of my wheel chocks (have enough room to mount it i think) im trying to use the space as best as possible. my EZUP will fit inbetween the bikes easily. also id like something on the plywood, paint, truck bed liner, diamond plate. jsut havent decided yet.total cost so fartrailer - $279 (on sale and 20% off coupon)spare tire mount - $15 (20% off)pressure treated plywood - $37carriage bolts and nuts - $64' of angle iron - $13$344 + taxi need to snag up a spare tire yet as well, but so far im under what i thought i was gonna be on this thing.

Mykill Posted January 14, 2013 Report Share Posted January 14, 2013 Nice work. The 12 inch tires on mine worked well. Quote Link to comment Share on other sites More sharing options...
Simplysix Posted January 14, 2013 Report Share Posted January 14, 2013 Looks good. I like the idea of using truck bed lined on the plywood. Remember to keep it in the garage for a while and let the plywood "dry out" before you seal it with anything Quote Link to comment Share on other sites More sharing options...
Firedog Posted January 14, 2013 Report Share Posted January 14, 2013 Looks good Ryan!And I wouldn't worry about the tires...the original Mini's ran with 10" tires! Didn't seem to be an issue for them Quote Link to comment Share on other sites More sharing options...
Firedog Posted January 14, 2013 Report Share Posted January 14, 2013 A couple of other questions:- Do you have an idea on total weight when it's loaded with both bikes?- Where did you source the hitch for your car (factory, aftermarket, home built)?- You mentioned the fenders, what would you have done differently?- And lastly, did you (or is it planned) to treat the underside of the plywood deck as well?

redkow97 Posted January 14, 2013 Report Share Posted January 14, 2013 (edited) Trailer itself is probably 300-350 lbs. Bikes can be rounded to 500 with gas. The whole setup should be around 1500, give or takeBalancing the bikes properly makes HUGE difference though. I moved my pit bull TRS back 4" and moving the trailer by hand (with bike or bikes loaded) got to be insanely easier on my back.

ohiomike Posted January 14, 2013 Report Share Posted January 14, 2013 Should measure the tongue weight. Quote Link to comment Share on other sites More sharing options...

Hard to believe but just a little shift could make the thing a dream or nightmare to tow. Quote Link to comment Share on other sites More sharing options...

After its fully loaded id liked to weigh it.I bought the hitch online, its a CurtI would have mounted the fenders before mounting the axel and suspension. Hard to mount them after the fact.I plan to paint the bottom side of the deck at some point. Quote Link to comment Share on other sites More sharing options...
RidersDiscount Posted January 14, 2013 Report Share Posted January 14, 2013 Wouldn't be a bad idea to buy spare bearings and seals for the in-case along with that spare wheel. Quote Link to comment Share on other sites More sharing options...
330racing Posted January 14, 2013 Report Share Posted January 14, 2013 Try spraying the plywood with plastidip. I live the stuff. Its tacky enough to offer grip. Quote Link to comment Share on other sites More sharing options...
madcat6183 Posted January 15, 2013 Report Share Posted January 15, 2013 Wouldn't be a bad idea to buy spare bearings and seals for the in-case along with that spare wheel.Highly recommend this, especially for that trip. Might even go with bearing buddies if you haven't, or buy good replacements and buddies, do all that in 1 swap IF you need to. Hopefully you dont.PS, did you talk to Andy today? Feel free to PM me about tire mounter pickup etc. Quote Link to comment Share on other sites More sharing options...
rollnhot Posted January 15, 2013 Report Share Posted January 15, 2013 HF trailers are pretty tough for the money spent. I have a 4x8 folder and work that thing like a borrowed mule,no issues. Regreased the bearings when new and thats the only thing it needed. Hauled 125 12x12 patio blocks no problem, enough metal roofing for a 2800 sq ft roof, that thing replaced my pick up truck. For around $300 cant beat it. Quote Link to comment Share on other sites More sharing options...
Kosmo Posted January 15, 2013 Report Share Posted January 15, 2013 Sweet set up !!! I will be at Jennings GP March 9 and 10 Quote Link to comment Share on other sites More sharing options...
RHill Posted January 15, 2013 Report Share Posted January 15, 2013 may want to add in a support for the fenders, they vibrate/resonate and supposedly are one of the first parts to fail on these trailers....I know the vibrate like hell on mine, so I used a bungee cord to dampen the vibration.

redkow97 Posted January 15, 2013 Report Share Posted January 15, 2013 I haven't had many issues with the fenders vibrating. Early on I noticed that the tires would scuff the fender supports, but I wrapped them with a layer of tape to see if that was common, or a fluke. That tape has been undisturbed for about 3 years now. So the fenders do vibrate some, but it hasn't been a problem on mine. Quote Link to comment Share on other sites More sharing options...
RHill Posted January 15, 2013 Report Share Posted January 15, 2013 Oh yeah, check the bolt pattern of your car vs the trailer. Mine fits, so I can use the spare in my trunk. I test fit it as well, the spare has to be installed dished out, and it will rub the fender, but that could be removed in a pinch. Saves hauling around a second spare.

TRMN8TR Posted January 15, 2013 Report Share Posted January 15, 2013 You got the spare tire mount at HF as well? I haven't seen those there but I need one. Quote Link to comment Share on other sites More sharing options...
