Hi,
I'm 99% sure if it was me, I'd go with the Bigfoot. There is only one major thing and a few "nitpicks" that might cause me to reconsider the decision, and even then, I'm not so sure I still wouldn't jump on it, especially if the price was right. The Bigfoot brand & reputation plus the heavier diesel chassis make a pretty tempting combination.
I noticed in the Bigfoot brochure that the Diesel chassis motorhomes were available with either an Onan propane (LPG) powered generator or the diesel powered generator (Quiet Diesel), both rated at 5.5 kW. My preference for an RV generator is that it use the same fuel as the engine of the motorhome. If you use the generator a lot, a propane generator can be a pain as it will require a lot of frequent propane refills. On the other hand, if you don't use the generator much, then it probably won't make much difference.
For us, we tend to run the generator most times we're on the road (either for A/C or heat) to keep the family comfortable. So used in that way, an LPG generator wouldn't be ideal for us.
The other thing I see that might be a bit bothersome is that it looks like you'll lose access to two(?) kitchen drawers when the slide is in? Maybe a cabinet door under the sink, too? Can't tell for sure. And access to the kitchen sink will be a bit encumbered as well. When we travel, we like access to everything in the kitchen without putting out the slide.
Both rigs have split baths, and while not my preference, IF I had one in my motorhome, I'd prefer a layout similar to your current rig, which I believe has the sink and the john on the same side of the aisle, and the shower opposite. I think the Bigfoot has the john and the shower together.
And I'm REALLY nitpicking now, but personally I'd prefer a dinette (which looked to be an option on the Bigfoot) to the folding table & chairs shown on the brochure.
But if that rig has a Quiet Diesel model generator, I'm pretty sure I could live with the other possible issues.
Good Luck and be sure to let us know what you decided!
