New Axle Alignment?

[Lumatic]

I finished putting in my new Dexters and hooking up the brakes. I can already see the trailer now tows straight and looking at the wheels they seem to be parallel and straight. As a general rule should I have the alignment checked, or an alighnment done?

PS. I did an earlier post about a brake wiring problem. Turns out the brake ground wire was in the wrong position in the 7 way. And for some reason the brake ground wire is red. The 2 red wires were connected to the left tailight psoition. As soon as I figured this out and connected the red ground wire to the ground position in the 7 way the brakes work perfectly This also means that I was unaware I was previously towing the coach sans brakes

As a first test if you have an 8 ft. florescent light bulb lay it up against the centerline of the tires. The bulb should touch all the tires for and aft. If you see more than an 1/8 gap at any of the contact points I would consider having the alignment. I suggest an 8 ft bulb because it is about the straightest thing the average person can lay their hand on. If that won't fit a 2 axle trailer a taught string and an assistant will.

Be very careful in selecting an alignment shop because they have to bend the axle tubes to do this. I would look for a truck axle shop that has worked on RV trailers.
