If the floorplan is a problem, DO NOT BUY. It will be a problem for others as well. If it has three or four slides, I would be buying the Heritage provided the condition is equal to the others. No matter how long the thing is, remember where the front end goes, the back will eventually follow. There truly isn't much difference between 45 and 40 feet, but there is a big difference in tag axle vs non-tag. Formerboater is correct, if you buy the best you can afford, you will be keeping it much longer and not losing multiple thousands when you go to trade off the one you bought that was almost, but not quite, what you wanted.
