Are there issues if conect toad's battery to RV's directly?

hi, i am new in this toad thing, so your opinion is appreciated. on my rv there is a 7-pole electric socket, one pole is always live with 12vdc. i am thinking if my toad battery positive terminal is fed from this pole, the toad battery will be parallelly connected to the rv battery pack, subsequently i will never need to worry about toad's power drain. do you see any problems by doing this? thanks.

This is very common. I've done it on my last two toads and it works just fine. For safety you should have an inline fuse at each end of the wire.

The " hot wire " in your RV plug would be for a battery charge in a trailer tow situation , your toad would have to be properly wired and fused to get the battery charging.
The " hot wire " in the RV will be fused near the source, and if the charge wire to the toad battery in the toad is not properly fused then ; in the event of a short ; provide power into your coach to burn up the wiring even if the RV fuse blows. You need to find the supply fuse in your RV and install a fuse of equal size , where you hook the wire to your toad battery.
And as always , other members type faster than I do.

Rather than a fuse, I use 30 amp auto reset circuit breakers. One is 8 inches from the battery terminal, the other is about 8 inches from the toad battery. It is wired through the Blue Ox coiled cable. No problems in many miles of towing. No need to use a thicker battery cable, you are maintaining the battery, not trying to jump start or fast charge it.

That is how my motor home-towed pair is wired, With one slight modification (Which may be in place on your tow vehicle already)

Battery---Circuit breaker-------wire to socket
Plug----wire to circuit breaker----Battery

I bought and installed the "Toad Charger" and it keeps my battery charged in my Wrangler.

thanks everyone for being informative... surfed on web and found a coiled boat trailer wire 7 pole to 5 flat pretty neat - i only use 4 wires for signal lights can modify the remaining one for power (about 14 gauge should be safe). will add a mini breaker 10a just to protect against short. don't think the charging current will be big tho. sounds cool?

One of the RV magazine writers recommended 30 amp auto reset breakers at both ends and 8 Ga wire. I found the breakers online for $1.35 each.
30 amp is way overkill for just keeping the battery up and would be more suitable for a charge line to an RV.
I'm actually in the middle of doing mine. Since the wire will be less than 15 ft. I can use 10 Ga wire. Just got the towbar done a couple days ago. Hopefully I can get the MH and towed done this weekend. Friends here from CA so time will be limited and we're headed on for the 4th so I need to get it done.

on a standard 7way to 7way jacketed wire the power line is 12ga, and signals are 14ga. 8ga indeed sounds like an overkill. i installed towmaster baseplates on honda fit and routed the signal wires from tail to front. those jobs are not bad, you can get it done in a day. the only thing is sometimes i have to wait for the parts ordered online .
