A lot of us want to build a teardrop trailer, but don't have the metal working tools or welder. By the time I buy a welder, tools, metal, axles, and all the other stuff, I'll be well into the price of a good new trailer.
We also want a welded trailer with square tubing, not a bolt together sheet metal trailer (no offense to H/F, etc..). So here's my question, why doesn't CampInn, Little Guy, or any other teardrop manufacturer build trailers (frame, axle, and wheels only - no body) for the teardrop home builder? There's already a market for it. Look at the number of people already building on Red, Harbor Freight, and Northern Tool trailers. These people will probably not buy a whole teardrop, but may be willing to buy the trailer portion and get a better quality product.
You know what we need that we are not getting when we buy a trailer and bolt it together. We want:
--FRAME--
*Welded frames with square metal tubing, not bolt together sheet metal.
*Option of trailer sizes 4 x 8, 5 x 8, 5 x 10, 6 x 10...
*Already welded on angles for bolting the teardrop to the trailer.
*Welded plates in all 4 corners to add the stabilizer jacks.
*Choice of adding stabilizer jacks or not.
*Option of a wire mesh platform on the front to put a storage box on.
*Option of a battery box support.
*Powder coated trailer.
*A hitch for a 2" ball.
*A 2" receiver in the back to hold bikes.
*A fold-up front jack
*Option to have a metal box sunk below the floor in the sleeping area for storage like so many teardrops have built in.
*An "A" frame tongue that's long enough to not interfere with the tow vehicle when turning corners.
*Removable Safety chains with the welded on connectors. Somewhere on this web site I saw that someone had welded on a loop that was threaded to install chains. Like welding a locking carabiner to the trailer and then opening the carabiner to install the chains.
--AXLES--
*Option of 3500 lb or 2000 lb axles
*Option of spring rate of axle springs.
*Option of brakes or not
*Option of Torsion axle or spring axle
*Optional Torsion axle starting angle (more height for the off-road builders, less height for the low riders)
*Axles located at optimal forward/aft position for most trailer loading, or maybe make the position adjustable?
--WHEELS--
*Normal sized tires (13" or bigger, no 12" tires)
*Option of aluminum rims on the wheels.
*Option of a spare tire mount and spare tire.
--OTHER--
*Lights on the sides of the trailer and flush in cutouts in the rear bumper/frame of the trailer.
*A 7 pin connector
*Fenders and support brackets that are welded or bolted onto the side of the trailer frame (no holes in the wall of the teardrop to let in water)
*Shipping
*A discount to me for coming up with this great source of revenue.

Did I miss anything?
The web site could have check boxes where we check off the items that we want and it shows us the price. We could E-mail for any other specifics.
I know this would cost more than the bolt together models, but should be cheaper than buying a bolt together and modifying it. I have my own guesses on price, but you may want opinions from others that have already built teardrops as to what they would be willing to pay to not have to build the trailer portion.
