transporter+trailer = Sunday driving ban????

hello! someone can help me here. I explain briefly the problem. we want to bring a ford eifel from the netherlands to us at the end of the week. our combi may not pull the cord so only our transporter remains (he has truck registration and is otherwise commercially useful), which alone 2,8t weighs incl. trailers and eifel we come over the 3,5t. at the registration point, the dekra and the government presidium was explained to us the lkw ́s over 3,5t incl pendant on Sunday not fa and since it is further like 50km away from the home we need a travel clerk! we only have the possibility to borrow a jeep and it costs an average of 300 euro plus km(and that is 1200 km back and forth). does someone know about you? urgently need a tip!please there must be another solution lg ivonne
