How to Select a Trailer Hitch
Class and receiver basics that sit beside the mirror decision on a first tow weekend.

Factory mirrors that look fine in the grocery lot can disappear a wide trailer the moment you leave the curb. Here is what matters: when you need more mirror than the door glass gives you, how to think about clip-on extensions versus full replacement-style mirrors, and the CURT extension we stock. Shipping is free anywhere in Canada.

If you cannot see down both trailer flanks and a lane beside the trailer, you need more mirror. Wide cargo trailers, travel trailers, and dual-axle utility decks are the usual triggers. Clip-on extensions can help many door mirrors when the glass and housing accept them. Replacement-style tow mirrors are a bigger install. Confirm height fit and housing style before you assume every extension clamps onto every mirror.
If flanks disappear, you need more mirror.
Clip-ons are simpler. Full tow mirrors are a bigger job.
Not every mirror accepts every clamp.
Extensions still need aim.

| Topic | What we tell shoppers |
|---|---|
| When you need more | Trailer flanks and adjacent lanes disappear in factory glass. |
| Clip-on | Extensions help many door mirrors when the housing accepts the clamp. |
| Replacement | Full tow mirrors are a bigger install for frequent wide towing. |
| Aim habit | Extensions still need a driveway aim check before the highway. |




In short: if trailer flanks disappear, add mirror; confirm extension fit on the housing; aim before the highway; and keep lights on the same pretrip checklist.
