What's the easiest way to mount a trailer box??
 

Pics would be great but how are most trailer boxes mounted? I'm buying a 49" x 15" x 15" to keep cleaning stuff and jack and tools and what not. I plan on mounting it along the I beam long ways, not sideways across the tongue. Same type of set up like your typical Myco. Problem is, it's an aluminum I-beam. So, what's the best way to do it. Does anyone may large enough U-Bolts to wrap around the I-beam? I don't think drilling through the trailer would be a good idea. Any ideas?

I would say to make 1/4" aluminum plates a few inches wider than the I beam, drill holes in them and use long SS bolts.

You guys are saying basically the same thing right? I didn't think of welding a plate. That's a good idea. Would an aluminum welded plate on the bottom support all that weight? I plan on putting a floor jack in there as well as tools and other heavy stuff.

Any other way that I wouldn't have to track down a welder and just do it myself. What about U-bolts on the back side of the box, wrapping around the ibeam and drilled through the box.

LOL..True.

Those manning trailers are freakin nice.

I get what you're saying now. and good call with the thru bolts / two plates. I do know a welder come to think of it.

I've been thinking of doing the same to my steel trailer. I have some scrap pieces of 3/16 thick 2x2 angle iron to weld into L brackets then either u bolt or weld to trailer. The box would then be bolted to L brackets. All the boxes I've been looking at are thin skinned so wouldn't want to just bolt through the box even with a backing plate.

No, I'm saying use aluminum plate instead of U bolts but basically used in the same way as the U bolts.
Then use the same plates inside the tool box. Kind of like the way engine mounts are mounted on stringers.

You definitely want to hold + support the toolbox from it's bottom. There are some L brackets out there for toolboxes. Here are some to get an idea:

For an easier internet search use the term Brackets for Installing Aluminum Tool Box

Note, always install thin foam or rubber strips between metal brackets and aluminum trailer frame. I (and many people of coarse) have seen the devastating electrolysis effects of steel parts not being isolated from aluminum trailers. The kits should come with it, but should doesn't mean it will, :)

To answer the question posed: stepladder

AH! Got it!!

thanks...I like that.

You good on the tire carriers, I see you have one

Yep. Though I still want to see if I can do that spare hub set-up like you have. I don't know how they're set up though.

Couple thoughts.
DO NOT mount the trailer tool box too low. You want is as high as possible so when you are on the crappiest ramp and the 'wrong' tide or lake level, you don't flood your tool box. I mounted mine too low, and regretted it as such a few times. I mounted mine by bolting aluminum box tube under the aluminum frame of the trailer, and bolted the box to those tubes. Again, that was too low for the boxes I used. Taller boxes might have been better.

Two schools of thoughts on double spare tires.
1) I like the idea of having double spares, and I always carried two spares. Jeff Jassby had Myco put dual spares with full spindles on his NorTech trailer years back, that actually performed as additional guides to center the boat on the trailer IF needed in a strong wind or current. If such were mine, I would have had white vinyl covers over them, and used them for the exact same.

2) However, sometimes it's beneficial to stand on your spare tire on the trailer to access or reach the bow, grabbing a line, washing, trans-versing, whatever. If you have a spindle, the tire/wheel will spin and you can't stand on it. As such, there is merit to having the spares mounted to a fixed flat mount above the trailer. They can still act as guides mentioned above as well. And just keep a spare full ready to go spindle in a sealed bag in the trailer tool box (which is what I did, and never ever used).

I saw this photo and always liked the set up. https://cimg0.ibsrv.net/gimg/www.off...039d3bf34f.jpg

Mine is mounted on my Manning like this but with 2 small metal bars welded to bottom of trailer.
I would suggest turning it where the door is facing up. Mine gets water in it every time I dunk. Maybe if door is facing up as I saw one done before if would not get water in.

My trailer has replaceable spindles, 5 bolts to remove and bolt a new one on if it gets damaged, no more replacing the axle.....:D

....your wife SOOOO needs to video you attempting this! Just sayin'!

*Let the Tank destruction project begin! Eeeek! LOL (love' ya man! :-)

I


i put 2 plates on the inside of the box to support it,spread out the weight.2 bolts ,its been there since 2003

Myco build the trailer with the ladder at the bow? I'd actually like to have a ladder too LOL Cant find a pre-fab one anywhere.

I've only found a few searching around under ' Boat trailer bow steps '

Here is one:

I did see that one. It's just not high enough. I think the only way is to have someone custom make one. I like these set ups. I think it would be beneficial to not have to crawl up onto the swimstep to get on the boat while it's on the trailer.

That Sport trail one looks cool. :)

Years ago, on OSO, I saw a pic of a ladder attached to the swing arm of the outdrive guard part of trailer. I thought that was cool if someone has this type of trailer..

Found it :)

That is awesome! I will be adding that

Yes, it is from Myco. The first Myco we had built didnt have a ladder but we later ordered one for it, so you could probably call Myco and have one made.
