Your axles jump from 2000 lb capacity to thirty five hundred capacity. So you're stuck with finding a weldor who will do the unthinkable and make you a four thousand capacity trailer or go with the standard seven thousand. I personally wouldn't have anything lighter than a ten thousand for hauling anything I cared about.
Something no one thinks about but..........it is a viable option.
Try to get a trailer that has the same bolt pattern for the wheels as the tow vehicle. That way carrying one spare, the one on the tow vehicle is the smart thing to do.
If you have a six lug pattern like on the pickemups and some four bys don't think that just because you have a six lug pattern they'll interchange. What you'll need to is make sure by trying your spare on the trailer. The biggest problem is the center hole for a six lug trailer is the same as a four wheel drive six lug. Where some of the regular pickemups have a smaller center hole.
This center hole problem also comes to play on eight lug wheels. You grab a new trailer wheel off off of your trailer and try it on your GM three quarter of one ton with the eight lug wheel. It fits. You're happier than a puppy with two tails.
But then out on the road you have a flat on the trailer so you proudly drop down your spare and uh oh, no workee.
Ford products, bite my tongue, have the big center hole like you need for trailers. So your options are to go with a Ford wheel spare on the truck or trim that eighth of an inch or less from the diameter of your GM wheel.
Many has been the fella that paid dearly for a set of chevy beauty rims with the five or six hole pattern so his car hauler's wheels would match his pride and joy pickemup's to find out no workee without torching the center hole that little bit. The same goes for the eight luggers.
Now on the GM four wheel drives it's not a problem. Just the two wheel drives, go figure.
But you can order your trailer from shops with a five on four and a half pattern (Ford car), five on four and three quarter pattern (GM car), five on five (GM pick up, Ford big car, GM big car, NASCAR), five on five and a half (Ford truck, old Jeep), six lug (most four wheel drives, import pickups, GM half tons). A lot of the times mag wheels come with the biggest center hole just so they will fit the largest group of cars possible. And if your mag wheels on the trailer match your pickemups, well now...............
