I think that I may have finally sold my 20' Motorhome and am ready to buy a tt. I have written before for advice on certain models but the deals on my motorhome fell thru. due to the bad economy & most people already having bad credit. Now I am seriously considering a new eco 718QB by Dutchmen/Thor. After reviewing their web site, it appears that this tt is well built. Has anyone owned one & if so, did it hold up. We put approx. 80,000 miles on our MH in about 6 years seeing the US so we do need one that will hold up well. We do try to maintain our rv well. Thanks so much for any help.
