Just purchased a Tropical T351. For the entire week of pre contract on this motorhome it was discussed the 350 Cat diesel that was in the coach. During this process of negotiating and dealing with the salesman, he gave me a brochure on the unit, marked on the brochure as a T350, and the brochure had only one engine in the specs, that was a Cat 350 HP.? I talked of it several times, but I cannot swear the salesman actually said it was a 350.? I mentioned it compared to the 300 HP in some motorhomes, the difference in power, etc. and he never corrected me that it was a 300. All through the week and all through the hour of contract signing I was completely sure of it being a 350.? I drove the unit home, and the next morning when I was taking the window sticker off, I noticed that it was listed as a 300. I was very, very disappointed.? I checked the brochure again, called Freightliner, gave the vin number, and low and behold it has a 300 for sure. Then I also, for reasons I cannot believe, I didn't see during the inspection the very large number on the back of the motorhome..."300 hp turbodiesel"? Now anyone will know from this, just how stupid and inattentive I was in this. In the excitement of getting this, I just simply somehow never noticed.? I have not a leg to stand on, it was on the sticker, and also on the unit that it was a 300. However, I had been told by a few people, (and I still do not know if it is true) but that I had 72 hours to return.? I purchased on Thurs. 3PM, and on Friday beginning at about 9AM I began calling the dealer, (who is 75 miles away) and leaving a message for a return call about the problem.? The salesman, nor the owner of the dealership would ever call back, (because I suppose that I had made the mistake of telling the person on the phone why I wanted a return call from the salesman) I again called on Saturday, with the same result of not being called back. Now it is Sunday, and if the 72 hrs thing is true, Sunday is closed.? What I would like to hear first of all...Does anyone know if I will be able to return or exchange at? this point? But, also, is there anyone who can encourage me about the 300 Cat diesel over the 350?? The price I feel was good, but maybe the 300 was the reason. Sorry, for this long one, but I am really "buyer remorsed" and would like to feel good about this whole thing. Thanks for any time from anyone.
