I've recently changed my tow car to a Mitsubishi outlander phev from a diesel outlander. I've had a successful trial run to Anglesey where i found the car performed much better whilst towing in cruise control with the car in charge mode. This ensured i always have battery power for any hills. Next week I'm traveling from Lancashire to Pembrokeshire. I'm not sure which route to take. The safest but longest route is M6,M5,M50 then A40 and back onto M4 near Newport. But does anyone have any experience in A49 to leominster, A4112,and A470 to Breacon then A40 through Llandovery and onto Carmarthen. Even better if someone has done this route towing a 1500kg van with a 2.4 PHEV. Thanks in advance
