Last year I drove the Roadtrek down to Panama, Central America and during the 8,000 mile roundtrip the Roadtrek was serviced twice, once in Mexico on the way south and once in Guatemala on the way north, and both times the mechanics were very impressed with the 4×4 conversion. More so than the RV components. Having said that,… an independent mechanic here in Phoenix, AZ … was VERY impressed with the 4×4 conversion, adding that of the many 4×4 conversions they had seen in the past this one, your product, was by far the most impressive, to include the heavy-duty brakes. Not my words, and I have nothing to gain from that but thought I would share with you that your product is very much admired. Again, thank you!
