Looking at my Onan, it is four bolts and it slides out, it should not take a genius to remove the thing. All of the service work can be done from the front of the thing.
I ended up with an Arctic Fox 865 with genset, a/c and a tad more of everything for much less than a poorly optioned Adventurer. The AF was deeply discounted off sticker.
I've noticed any conversation on campers ends up with people harping about how brilliant they are for buying a Honda generator and building a rack to haul it around on in lieu of a built in unit. You got a Honda, good for you. The actual question is, "What would you order?"
An oven can be handy, but I see it being hardly used for most trips. If deleting it saves you money and you never want to make cookies, pizza or biscuits then skip the oven.
A microwave makes a great bread and cereal cabinet and if you have one it makes an awesome microwave when you need it. I would not refuse one or refuse to buy a camper because it had one.
I think Eagle Cap is as nice as Arctic Fox, the only real difference might be hand flush vs. foot flush toilet and head room over the bed. With the rounded nose, AF has about 4 more inches of headroom which is great for tall guys.
Before I ordered one especially for me, I'd shop every dealer in the region for an in stock model with everything I wanted for less money. Unless you want to be that guy that pays retail and is **** glad to do it.
