It's inspirational.

I was measuring my carhauler on Saturday and brainstorming what I want to do with it. I think I may just shorten the deck from 16' to 12'.

Just saw your trailer/dolly build thread and read through it all.

Fantastic job all the way through.

Thank you sir! If I had to do it over again I would only change a few things. I would add more zip tie brackets before paint to secure wiring.

I started conversing with Brennan Metcalf a few months ago, as he wanted to build something similar. He's an engineer though, so it's a far better planned and executed trailer. He designed it all in CAD and sent it to a laser cutter for most of the cutting. When he received the steel from the laser cutter, he built the whole trailer over two weekends and a few hours each night after work. He can easily modify the plans for different size trailers, so if you're interested in building one, you might contact him. His build can be seen on Instagram.

I drove over and looked at Brennans. I like yours better, even if it's 200lbs heavier 😁.

Brown Santa brought some upgrades.

I had some lug nuts that kept backing off and ruined a wheel. I decided to change out the hubs and wheels for 8 lug. This will match my dump trailer tires/wheels, so each time I replace a tire it will go on the Jeep Dolly, and the Dolly will give up its tires to the dump trailer. That will keep the freshest tires on the single axle trailer. I've got some trips coming up that will put some miles on this Dolly this year.

So, I ****ed up. The reason my lug nuts backed off is because I put the wrong wheels on the trailer. On the upside I'm glad I did, because then I got the chance to fix some other issues I just found. Issues that were about to cause me trouble.

As you can see, 3 lugs are broken off. I caught this back in August right before a trip. I thought I just hadn't been vigilant enough about checking my lug nuts. Only one lug was missing when I caught it. The other two fell out when I took the wheel off last night.

This is why:

The hub is not supporting any of that wheel. It relies entirely on the lugs. The new hub supports the wheel correctly.

I ordered new 8 lug hubs and was surprised that they came with the backing plates and brakes, but I'm damn happy that they did.

I bought this axle used, and whoever put it together missed some important things. Like weld bb's on the inner seal surface.

Which could lead to a seal failure and contaminate the brakes with grease.

They also smashed the brake wiring under the backing plate nut. That explains why I had an intermittent brake connection issue.

But she's all better now.

Trailer axles are really very simple. I'm super glad I found these mistakes and corrected them, even if I'm embarrassed about the wheel issue that I personally missed.

8 lug axles look so cool on trailers. Especially gold trailers 🤣
They do look way more burly than 6 lug.

Also, interesting tech that I found out in this process. These 6 and 8 lug hubs use the exact same bearings and seals. I expected the inner seal to be a different size for my spindles, so I ordered the smaller seals (2.125" vs 2.250") separately. I'd don't have to use those, so I'm glad they were cheap.

898 miles this week behind the new gas truck. I was hoping to pull down 11 mpg but the wind was pretty bad on both towing days. I averaged 10 mpg going down, 9.8 coming back, and 9.9 for the whole trip. I averaged 10.5 leaving Moab until I hit I-70 and had a stiff headwind all the way home. I think I could get 11 mpg without all of the wind.

Overall I'm quite happy with the new truck. I do want some lighter front springs, but it had zero problem pulling the Jeep and Dolly up all of the hills as fast as I could handle it.
