Every vehicle has it's own plus and minus's and luck has a lot to do with how well the reliability goes.
I would agree with the Lemon theory based only on the good repair history of the previous two vehicles of the same make/model I owned, if it were not for the fact that another member here who pulls with the same vehicle has had to do a lot of the same work/replacement parts I had to do on mine and they are also towing a trailer just under its tow spec.... they also have a high number of tow miles on it as I did. They feel its just part of the price one pays for towing and to be expected. Of the 60,000 miles on mine about 65% or more of the miles were towing miles. And yup it was services regularly and it had all the fluids changed more frequently than required per the manual and it had an overside transmission cooler.
Bottom line is towing is hard on a vehicle and the closer you are to the towing spec or the more over you are, the harder it is going to be on it.
