Hey Larry, we actually sell jacketed 7-way wiring with the part # DW04914-1 by the foot. This would allow you to have all of the 7-way circuits to the back of the trailer like you are needed. You would just need to order a quantity of this that you need in overall feet. So for example, if you need 20 feet just order a quantity of 20.

@LarryS We have videos for replacing 7-ways at the front of a trailer but we don't have anything oddly enough for from there to the rear of the trailer. Since every trailer is different though a video probably wouldn't be super helpful anyway.

Answer 1

The best option we have that will fit your wheel and work well is the Lionshead tire part #LHWL101. The quality and construction of this tire is unmatched but I really like about it is the fact it has a 75 mph speed rating which is higher than most…

Hey Carl, welcome back! You've done a great job of identifying the Lance 6-pin wiring functions and matching them up to the etrailer Trailer Wiring 7-Way Upgrade Kit w/ Junction Box item #e99011. You don't need to worry about the blue wire…

Hey Larry, yes the Dexstar trailer wheel part #AM20440 that you referenced was designed to be used with lug nuts that have a 60 degree angle conical seal like the #DE55KR which I really like because they are solid stainless steel. That means they…

Hey Larry, since trailer wheel and tires aren't normally balanced the Loadstar ST205/75D14 Bias Trailer Tire with 14" Black Wheel #AM3S451 are not either. Generally there's not much of an upside to having them balanced so to keep costs…

Answer 7

The 6-pole sockets that we carry can only handle up to 12 gauge wire so the only way to really swap away from Lance's proprietary connector would be to treat it like a standard camper and switch to a junction box and 7-way connector like parts…

Hello Pat, thanks for getting in touch. We deal in all sorts of cords and plugs for trailers, so we most likely will have what you are looking for. Can you tell me exactly what you are needing this cord for? What kind of plug is on your truck…

Thanks for writing in, Marco. The plug that Lance uses on their campers is a proprietary design, and unfortunately, there’s currently no aftermarket adapter available, at least not one that we carry. According to the Lance owner’s manual, the plug…

Answer 10

Lance does have a proprietary plug, but many customers see a standard 6-way or 7-way round and notice it doesn't fit their factory 7-way as well. I've attached an article to help if you have one of the 7-way or 6-way round connectors which we…

Answer 11

A junction box/7-way plug kit like Epicord #277-000141 or #HS381-9000 lets you convert the camper to match the 7-way RV blade type connector format. This avoids the extra connection points and potential trouble spots from using separate adapters.…

The closest pre-mounted wheel and tire we have to the #AM3S451 but with a radial tire instead is the Kenda Karrier ST205/75R14 Radial Trailer Tire with 14" Black Mod Wheel #AM32131 which has a radial tire and similar black powdercoated wheel.…
