At the shop we get 2 are 3 trailers a year . The insurance companies don't want to pay up. So any modification you've done that they consider not safe they don't pay. so the whole time while sitting at the shop there's being storage charge. There's no work being done you're going to get charged for an estimate. The trailer won't be released until the bill is paid. On the 30th day lien paperwork will be started. With extra fees that will add up very fast. I have seen only one that this has happen too the owner get it out.
Was not posting about the lug nuts. The larger the outside circumference the more centrifugal forces placed on the bearing . Those going with large tires normally step up to a 3500 pound axle for the larger bearing surfaces .many cheap axles have cast spindles
So hope you all the luck in your build.

Yes it can be extended in width and length with probably smaller than 2x6 or 2x8, which will make it easier to meet your gvw goal. Height of floor may not be a concern for you, but most people like being able to sit in door. I underslung axel to further lower it.

I had antipited changing just wheels and tires to 14" but now would like to add brakes so planning on changing axel (can't add brakes to NT axel).

I don't know about current production models but the (black) paint on mine faded a lot fast. The Krylon I used for added steel is fine. I plan to paint entire frame before long.

There is a trade off between ground clearance (i.e. lift) and convenient galley counter height while maintaining adequate space under the counter for cooler/12v fridge stowage. One solution might be to do a split level countertop, or just partial width counter.

Lift and larger tire diameter.

I used the Northern Tool no floor landscape trailer. I paid a local welder to add diagonals, and lengthened the tongue. That cost $275. Add the $425 I paid for the trailer. Welder guy says, "I can build you a much better trailer for what you have in this". So, haven't taken him up on it yet! But I am waiting for lumber cost to go down!

I extended tongue on mine for $25 piece of steel tube. There were other changes including planned axel, wheel, and brake upgrade, but killer for me would have been registration. Easy in some states, killer in others. Maybe some people like standing in line at DMV.

Maine rego's are apparently available mail order no inspection.

You still need a vin. In NYS for weight up to 1000 pounds you need a lot of paperwork to get that and only can get it when registering. Over 1000, more paper and inspections at their convenience. I have no patience for DMV bureaucracy.

Did you take a look at this in the Build Journals?

I am building a 6'6"W x 9'6"L x 6'3"H wooden canned ham on the Northern Tool 5 x 8. The only modification I made from trailer frame instruction was to mount the axle back about a foot from original position. The floor is 3/4" ply that overhangs about 9" in each direction, and is reinforced underneath the perimeter by 2x4's. It is just barely campable at this point, and I have towed it about 300 miles. It seems fine so far. I plan to start a build thread for it later this week.

One thing I would caution about is making sure all the nuts and bolts are snugged down both before you start the build, and before departing for the first time. I had them pretty tight on trailer assembly, but my initial camper build on the trailer ran into problems, and it was a few years before the I got around to building the current camper. In the mad rush to get out for our trip, I somehow missed going back and checking the nuts and bolts, as I discovered to my misfortune along the way. Definitely make sure you have them nice and tight. Check periodically along the way to make sure nothing loosens up, and carry something with you to tighten them up if need be.

After the first problem, I tightened up everything up until it was quite snug, but after about 1200 miles one of the bolts holding the coupler to the tongue had loosened up, and around 2000 miles I noticed one of the lug nuts missing from the wheel. So give the trailer a once-over whenever possible, and carry something to tighten things up if necessary.

Thanks for the recommendation. I actually had purchased a tube of it, and was planning to use some on some of the bolts (but not the lug bolts!) when I would snugged them up after getting it campable. I'll put more details in my eventual build journal, but long story short get enough sleep, or coordination, judgment and memory can all really suffer.

Can you share some pictures of this?

As for the Loctite..."Loctite threadlocker blue is designed to easily be replaceable with common tools, whereas red is a more permanent fix". I only use red Loctite when repair manuals recommend it, otherwise I go thru blue Loctite like water... OR use lock washers OR use nylon lock nuts.

I took a HF super duty kit (4x8) that I got on craigslist years ago and used the rails as steel stock to reconfigure to a 5x10 frame via cutting\welding\stitching together to make longer rails. The middle 4 cross bars are added 2"x1/8" hot roll steel angle. Used a NT axle appropriate for 5ft frame (think it was 58-59" spring centers). Used the same tongue bars welded to a HF 50deg A-frame coupler. Springs (and I think the hanger kit) from trucksprings.com 700lb(ea) double eye. Still using 12" wheels with radial ST tires.

Floor overhangs the front corners.

I imagine something could be done in a bolt together situation, though would probably need to take a bit of a different approach... Attaching the tongue might be tricky.
