In my 38 years of racing, I've had quite a few car trailers ... 30+ ... from open flat bed 16' to 53' Nascar "transporters" ... from budget to luxurious ... and everything in-between.
I had one trailer the walls separated from the frame !
I have come to the conclusion that ...
A. You get what you pay for ... most of the time.
B. Nothing wrong with a lower cost trailer if you're not going to use it much & can protect it from the elements.
C. If you're going to use it & want it hold up, for Pete's sake buy a good one.
D. Really take the time to make sure it fits your needs.
E. If you need to cut the budget, cut the frills not the quality of the structure.
F. Get more brakes than you think you need.
G. If you have one built ... go see the factory first. Lot of tell-tale signs where they're built.
I would add a few tips from experience:
* Torsion axles ride better than spring axles (beats up your car & stuff less).
* Air rides better than anything else, but that's for bigger trailers than you're looking at.
* Get the longer tongue. 5' is much better than 4'.
* Consider resale when shopping brands. Higher end brands hold their value better.
* Ignore "maintenance free bearings". All that means is you need to replace them instead of inspecting & repacking them.
* Be a little cautious of buying a bigger trailer than you need. If there is space, you will fill it & that adds weight.
* Will your truck tow it?
* Nothing is worse to drive ... or more dangerous ... than an unbalanced trailer. Too much or too little tongue weight is bad.
Lastly ...
* If you live on the West Coast, especially in California, TPD is a great option. Not only do they hold up amazingly well over 10-15-20 years ... the resale is awesome too. I've had 4 TPDs. Best short trailer I've ever owned.
