Welcome George to the forum!
If the 93 Safari Serengeti you are talking about is the one on RVT.com, it looks nice! But, it is priced about double what it is worth! Not too familiar with the Safari Coach's, but with leaf spring suspension, hydraulic brakes, propane generator, for that money you can buy a very nice Monaco, CC, Newmar, with full air ride, air brakes, diesel generator, and on and on!
Get out there and test drive them all, and make your own choice! Only you know what you want and like!
Depending the weight of the coach, is if the 250 HP will be enough for you!
The ratio is 1 HP for 100 lbs, so if this coach weighs 25,000 lbs. or less it will perform good! So They Say!
Retired, and "Always on Holiday!"
