My wife and I are partial to 46 (45 is almost the same). Despite what was said above, the side-to-side level was taken care of with one 2x10 (now using Anderson levelers which are even easier). The site has very good privacy - wide and can hardly see through the foliage to adjacent sites. Also nice is that, since I do a dump run mid-stay, the dump station is in easy pull range for the portable tank. Don't get 47... the layout is wrong (fire pit/eating area on wrong side... have to pull in from the opposite end and be on the road to unhitch so your awning and that area align).
