We went from a 36 foot FW to a 39 foot diesel pusher. We needed an upgrade on the existing tow vehicle and by the time we priced a new one, it was 65 K. We started looking a diesel pushers with the thought of towing our Ford Explorer behind it. We ended up with the 2007 Itasca 39K with all the accessories to tow the Explorer for about 85K.
That was a great decision. The floor is flat where the FW we had two steps to climb to get to the bedroom or bathroom. We can access the entire MH with the slides in. My wife can sit on the comfortable couch while underway. Self leveling. Water in the water heater is hot when we stop. Many more features we have come to love. We had solar panels and AGM batteries installed and have been able to boondock for 6 days straight.
Many things to consider, but we are happy with the choice we made.
