You should have no problem getting into the trailer park as far as size goes. The problem we had was finding the correct turns to get there. Do you have Microsoft Streets & Trips? I can send you the route so you can plug it into S&T. Or I can try to explain it. We took 132D and got off at the correct exit but it is one of those cloverleaf things where they have cloverleafs overlapping cloverleafs. We made wrong turns and found ourselves going the wrong way. Once we got to town we could not find the TP due to construction and torn up roads and detours. Finally parked and walked to find Mina who is the owner and she got in her car and led us into the park. She even moved detour barrels and just said "follow me". She is a very nice woman and maybe if you call you can arrange for her to meet you to lead you in - she does fine in English. I think I posted on here years ago and maybe on the Church website.
We took the new road but not the Arco Norte. On the map there is another road I show as 5D but don't know if that is correct. It goes from 57D (Queretaro Autopista) to 85D (Pachuca) and 132D near Ecatepec de Morelos. I shows as a totally straight line for much of its route. It starts near Coyotepec and Huehuetoca. I takes off from 57D further south toward Mexico City than Arco Norte - no problem with Mexico City traffic so no worries.
I will say that Teotihuacan is well worth the effort and maybe more than one day exploring. From there we were able to hire a guide to go into Mexico City and the Anthropology Museum which could take a few days too. Mina says take the bus and then the subway into Mexico City and she does it all the time but we figured it was worth it to hire a guide.
This is a nice place to hang out for a bit unless a Quebec Caravan of 22 RVs shows up to a park with 18 spaces. Mina had us park in her garden and hook up to her house - and the caravan had a party with mariachis so it turned out ok though quite crowded - truth be told we had a pretty nice spot in the garden.
